Scope

Covers all major animal exploitation industries operating at meaningful scale in New Zealand: dairy cattle, beef cattle, sheep (meat and wool), farmed deer (venison and velvet antler), pigs, poultry (broilers and layers), aquaculture (Greenshell mussels, King salmon, Pacific oysters), marine capture fisheries, horse racing and breeding, and rodeos. Animals used in research, teaching, and testing operate under a separate regulatory framework and are included in scope. Live export of livestock by sea for breeding operated until 30 April 2023, when the Animal Welfare Amendment (Livestock Exports) Act 2022 took effect, prohibiting live sea export. Fur farming is absent. Companion animal services are excluded except where structurally tied to breeding or trade.

System Overview

New Zealand holds a globally significant position in export trade of dairy commodities — particularly whole milk powder and butter — despite a relatively small national herd, and is a key global exporter of sheepmeat and farmed venison. Total livestock numbers declined from approximately 50.9 million in 2002 to approximately 33.8 million in 2024, driven primarily by a long-term reduction in sheep numbers from approximately 39.3 million in 2003 to approximately 24.4 million in 2023. The country functions predominantly as a producer and exporter of animal products — dairy, red meat, wool, seafood, and by-products — with domestic consumption substantially smaller than export-oriented production. New Zealand is the sole global supplier of trademarked Greenshell mussels and produces approximately 75% of global King (Chinook) salmon. Enteric methane from ruminants accounted for approximately 81.4% of reported agricultural emissions in 2021; agricultural emissions fell approximately 2% in 2023 due to reduced livestock numbers. Major processors include Fonterra (dairy), Silver Fern Farms, Alliance Group, Anzco Foods, and AFFCO (red meat).

Key Systems

Dairy cattle. Dairy cows are raised predominantly in pasture-based systems with seasonal calving, with increasing use of supplementary feed and wintering barns in some regions. The system produces milk for processing into whole milk powder, skim milk powder, butter, cheese, and other export dairy commodities. Surplus calves — primarily dairy-breed males — are slaughtered at days old as bobby calves; total cattle slaughter in 2023 was approximately 4.69 million head including approximately 1.97 million calves. New Zealand holds a large share of international seaborne trade in whole milk powder and butter relative to its herd size.

Beef cattle. Beef cattle are raised predominantly on pasture in extensive or semi-extensive systems, including dedicated beef herds and cull dairy animals. Production serves both export markets — integrated into high-value and manufacturing beef supply chains in North America and Asia — and domestic consumption. Cattle numbers were approximately 3.7–3.8 million head in 2023–2024.

Sheep — meat and wool. Sheep are kept in extensive grazing systems for lamb, mutton, and wool production, with some finishing operations near processing plants. Wool — including crossbred strong wool — is a named co-product alongside meat. The flock declined from approximately 39.3 million in 2003 to approximately 24.4 million in 2023; combined sheep and lamb slaughter in 2023–24 was approximately 22.2 million head, indicating significant destocking alongside stable export volumes. New Zealand is a key global sheepmeat exporter.

Farmed deer. Red deer and other deer species are farmed in fenced pasture systems for venison, velvet antler, and co-products; production models are extensive to semi-intensive. New Zealand is one of the world’s largest producers and exporters of farmed venison and velvet antler — a globally unusual position in the scale and commercial organisation of deer farming.

Pigs. Pig production uses intensive indoor systems — including farrowing and growing sheds — alongside smaller outdoor and free-range operations. Pigs on farms decreased from over 320,000 in 2009 to approximately 243,588 in 2024; annual processing was approximately 630,000 pigs in 2021–2022, with approximately 67% processed in the South Island. The sector supplies domestic pork, bacon, and ham markets, supplemented by imports.

Poultry — broilers and layers. Broiler production is highly intensive using large indoor climate-controlled sheds. Layer hens are kept in barn, free-range, and remaining colony cage systems subject to ongoing regulatory phase-outs. Approximately 3.76–4.15 million hens for egg production were recorded in 2023–2024. New Zealand is not a significant poultry exporter; production primarily supplies domestic demand.

Aquaculture — Greenshell mussels, King salmon, and oysters. Greenshell mussels (*Perna canaliculus*) are produced in coastal marine longline farms; King (Chinook) salmon (*Oncorhynchus tshawytscha*) in marine cages; and Pacific oysters on racks in coastal waters. Production in 2023 was approximately 93,000 tonnes of Greenshell mussels and approximately 14,500 tonnes of King salmon. New Zealand is the sole global supplier of Greenshell mussels and produces approximately 75% of global King salmon. Government plans target open-ocean salmon consents of up to 75,000 tonnes by 2035, representing a major planned expansion.

Marine capture fisheries. Commercial wild capture fisheries operate in New Zealand’s Exclusive Economic Zone using trawl, longline, purse seine, and other gears under a quota management system. Target species include hoki, orange roughy, snapper, and other inshore finfish and invertebrates. Approximately 81,811 tonnes were landed in one quarter of 2024 across 37,000+ fishing events (Fisheries New Zealand). The sector employs approximately 6,100 people in core production and approximately 4,850 in processing.

Horse racing and rodeos. Horse racing and breeding are named in scope as significant commercial systems. Codes of Welfare for rodeos are issued under the Animal Welfare Act 1999, confirming rodeos as a regulated commercial animal use system in New Zealand.

Live export by sea — terminated. Until 30 April 2023, live cattle, deer, goats, and sheep were exported by sea for breeding, with approximately 134,722 live animals exported in 2021. The sinking of the Gulf Livestock 1 in September 2020 — with the loss of 41 crew and approximately 6,000 cattle — contributed to political and regulatory pressure leading to the Animal Welfare Amendment (Livestock Exports) Act 2022, which prohibited live sea export from 30 April 2023.

Research, teaching, and testing. Animals are used in research, teaching, and testing under Animal Ethics Committee licensing; numbers are reported annually by MPI but are small relative to agricultural animal use.

Scale & Intensity

Total livestock: approximately 50.9 million (2002); approximately 36.2 million (2022); approximately 34.6 million (2023); approximately 33.8 million (2024, down 2.4% from 2023) — declines driven by reductions in sheep (−3.2% between 2023 and 2024) and deer (−4.4%) (EHINZ). Sheep: approximately 24.4 million head (2023); combined sheep and lamb slaughter approximately 22.2 million head in 2023–24 (MLA). Beef cattle: approximately 3.7–3.8 million head (2023–2024); cattle slaughter approximately 4.69 million head in 2023 including approximately 1.97 million calves. Pigs: approximately 243,588 on farms (2024); approximately 630,000 processed annually. Layer hens: approximately 3.76 million (2024), down from approximately 4.15 million (2020–2021). Aquaculture: approximately 93,000 tonnes Greenshell mussels and approximately 14,500 tonnes King salmon in 2023. Livestock density approximately 274 animals per km² of farmland in 2022 (EHINZ). Agricultural GHG emissions fell approximately 2% in 2023 due to reduced ruminant numbers (Ministry for the Environment).

Infrastructure & Supply Chains

Fonterra dominates dairy processing and export, aggregating milk from farms daily via tanker networks into large powder, cheese, and butter plants with integrated drying, storage, and containerisation connected to ports. Open Country Dairy is a secondary processor. Red meat processing is handled by Silver Fern Farms, Alliance Group, Anzco Foods, and AFFCO (Talleys Group), operating multi-species slaughter, boning, rendering, and cold storage plants distributed near livestock regions across both islands and functioning as export-certified chokepoints. Poultry processing is concentrated in a small number of vertically integrated companies running hatcheries, grow-out farms, feed mills, and processing plants. Aquaculture infrastructure includes marine farm sites in coastal regions, shore-based processing plants for mussels and salmon, and export-oriented cold chain systems through ports including Tauranga, Nelson, and Timaru. Capture fisheries rely on inshore and deepwater vessels using ports with unloading, chilling, and processing facilities; Seafood New Zealand is the peak industry body. Meat processing plants are limited in number relative to export-certified capacity, making them structural chokepoints for national livestock slaughter.

Regulation & Enforcement

The Animal Welfare Act 1999 (amended 2015 to recognise animals as sentient) is the primary welfare statute, with detailed minimum standards in 16 MPI-issued Codes of Welfare covering dairy cattle, sheep and beef cattle, pigs, layer hens, broiler chickens, rodeos, painful husbandry procedures, and other categories. Enforcement powers are held by MPI animal welfare inspectors, SPCA, and New Zealand Police, with MPI leading production animal enforcement. The Resource Management Act 1991 and amendments govern environmental effects of intensive farming. The Fisheries Act 1996 establishes the quota management system for commercial fishing. The Animal Welfare Amendment (Livestock Exports) Act 2022 prohibits live sea export of livestock from 30 April 2023. A University of Otago academic study of Animal Welfare Act enforcement documents reliance on complaint-based and risk-based inspections, under-resourcing of agencies, and partial inspection coverage of commercial farms and slaughter operations. Enforcement relies on evidence of “unnecessary or unreasonable” suffering, with relatively few prosecutions compared to total animal numbers.

Public Funding & Subsidies

Direct per-animal subsidies are limited; support operates primarily through general agricultural policy, research funding, and export promotion. Public investment supports infrastructure and innovation via MPI and government-industry partnerships, including government backing for open-ocean aquaculture development targeting NZD 1.4 billion growth potential by 2035. Export credit and trade promotion through New Zealand Trade and Enterprise facilitate market access for dairy, meat, and seafood exporters. Environmental and climate programmes fund agricultural GHG mitigation research, providing indirect support to livestock industries. Specific programme-level subsidy amounts disaggregated by species or system are not consistently reported in accessible public documents.

Labour Conditions

Agriculture has among the highest workplace risk profiles in New Zealand: in 2024, 16 work-related fatalities on farms were recorded alongside 191 serious injuries and 1,491 injuries causing more than a week away from work (WorkSafe New Zealand via SafeAg Systems). WorkSafe New Zealand is the primary workplace health and safety regulator across farming, meat processing, and related sectors. Seafood sector employment: approximately 6,100 in core production and approximately 4,850 in core processing. Common occupational risks include injuries from machinery and animals, musculoskeletal disorders from repetitive tasks and heavy lifting, and exposure to biological agents. Larger meat processing plants and some dairy operations have union presence; detailed sector-specific unionisation rates are not comprehensively reported.

Environmental Impact

Enteric methane from ruminant animals accounted for approximately 81.4% of agricultural GHG emissions in 2021; nitrous oxide (from animal urine and dung) approximately 16.3%; manure management methane approximately 4.4% (NZ Agricultural Greenhouse Gas Research Centre). Agricultural emissions fell approximately 2% in 2023, continuing a declining trend since approximately 2014 enabled by reduced livestock numbers and productivity gains. Livestock density was approximately 274 animals per km² of farmland in 2022. Nitrogen losses from intensive dairying — from animal urine and dung to soil and waterways — are identified as major contributors to water quality pressures in national and regional environmental assessments. Aquaculture generates benthic effects from marine farms; capture fisheries generate seabird and marine mammal bycatch, with Fisheries New Zealand’s refreshed reporting making seabird and dolphin capture data more accessible. Marine shrimp aquaculture interactions and freshwater impacts are not the primary concern at NZ scale — benthic effects of mussel and salmon farming in coastal zones are the documented focus.

Investigations & Exposure

The sinking of the Gulf Livestock 1 in September 2020 — carrying approximately 6,000 cattle and 43 crew, with 41 crew lost — generated sustained media and policy scrutiny of live export by sea, contributing directly to the Animal Welfare Amendment (Livestock Exports) Act 2022 and the 30 April 2023 ban on live sea export.

A University of Otago academic report on Animal Welfare Act oversight, compliance, and enforcement documented complaint-driven and risk-based approaches, MPI and SPCA enforcement responsibilities, and constraints on proactive inspection capacity for production animals.

SPCA and SAFE (Save Animals From Exploitation) have documented gaps between legislative standards and enforcement outcomes, citing under-resourcing and selective application of Codes of Welfare. These organisations have raised concerns about farrowing crates and intensive housing systems.

Fisheries New Zealand refreshed its bycatch reporting system to provide more accessible data on seabird and dolphin captures across commercial fishing operations, with quarterly data from 2024 showing 37,000+ fishing events and 81,811 tonnes landed in one quarter.

Industry Dynamics

Sheep numbers have declined approximately 38% since 2003 while sheepmeat export volumes and value have been maintained through productivity gains and product shifts, indicating structural destocking without proportional export decline. Dairy has maintained output through higher per-cow yields despite peak herd numbers being passed. Red meat processing is consolidating around major processors. Aquaculture is targeted for significant expansion — particularly open-ocean salmon farming — with government consents targeting up to 75,000 tonnes by 2035 from a current base of approximately 14,500 tonnes. Capture fisheries are managed under quota with ongoing adjustments to reflect ecological and market pressures. The live export by sea system is legally terminated.

Editorial Correction Notice

Scale and intensity — source alignment: Livestock population figures are reported across different years and sources (EHINZ, MLA, Beef + Lamb NZ, USDA GAIN) with occasional definitional differences; figures should be updated against primary Stats NZ and MPI releases as new data become available.

Scale and intensity — slaughter disaggregation: Slaughter statistics by production system type (e.g., indoor vs pasture pigs, colony vs free-range layers) are either not publicly available or withheld under the Official Information Act, limiting system-level granularity.

Primary animals — aquatic species: Chinook Salmon (*Oncorhynchus tshawytscha*), Mussels (Greenshell, *Perna canaliculus*), Oysters (Pacific), Hoki, Orange Roughy, and Snapper are assigned based on explicit naming as primary New Zealand aquaculture and capture fisheries species. Per the universal linking convention, relationship fields are populated regardless of whether target CPT records currently exist; shell records are created on demand. Chinook Salmon is structurally distinct from Atlantic Salmon and requires its own CPT record.

Primary animals — Deer: Deer are assigned based on explicit documentation of farmed red deer for venison and velvet antler. The Deer CPT record should reflect the farmed deer context distinct from wild deer.

Key industries — velvet antler taxonomy gap: Velvet antler is explicitly named as a product of New Zealand’s deer farming system. Velvet harvesting — the removal of antlers in velvet stage from living deer — does not map to any current Industries taxonomy term. It is not covered by Secretion & Gland Harvesting (which covers body secretions and glandular extracts) or by existing fibre or by-product terms. This represents a taxonomy gap for review. The velvet antler system is captured under Meat in the interim as part of the overall deer farming industry assignment.

Primary practices — Caging: Assigned on the basis of layer production, where the research explicitly names “remaining colony cage systems” alongside barn and free-range options. Colony cage is explicitly named.

Primary practices — Live Export: Live export by sea is legally prohibited from 30 April 2023 and has not been assigned as a current primary practice. The terminated system is documented in scope, key systems, and investigations.

Primary practices — Fleece Harvesting: Assigned on the basis of the sheep system, where wool — including crossbred strong wool — is explicitly named as a co-product alongside lamb and mutton.

Labour conditions — disaggregation: Labour injury and demographic data specific to individual animal exploitation subsectors (meat processing vs dairy vs aquaculture) are not fully disaggregated in accessible national datasets; sector-specific conclusions rely on industry and regulator summaries.

Public funding — subsidy specificity: Specific programme-level subsidy amounts disaggregated by animal species or system are not consistently available in public documents; the scale and distribution of support should be treated as indicative.

Primary Animals: Records for Deer (if different from Musk Deer), Chinook Salmon (if different from Salmon), Mussels, Oysters, Hoki, Orange Roughy, and Snapper need to be created to link this record to.
