The High Court has ruled the use of farrowing crates for pigs unlawful and wants changes to the legislation.
Two animal welfare groups, SAFE and New Zealand Animal Law Association took the attorney general, the minister of agriculture and the national welfare advisory committee to court in June saying the use of farrowing crates and mating crates breached the Animal Welfare Act 1999.
Farrowing crates are cages that keep a sow in a confined spot during the final months of her pregnancy and while she is suckling her piglets.
In its decision out on Friday, the court said the agriculture minister must consider new regulations phasing out the use of farrowing crates and mating stalls, and improve minimum standards.
