Of the 4.1 million hens farmed for their eggs in New Zealand, 2.3 million are kept in cages.
Battery cages, which house about a third of the national flock (1.1 million hens), will be illegal in New Zealand from 31 December 2022. Colony cages will however remain legal, despite the vast majority of New Zealanders opposing them, and many countries around the world banning them.
A 2020 Colmar Brunton survey found that 76% of Kiwis polled did not support the caging of hens. Thousands of New Zealand businesses have taken a stand against caged hen farming by pledging to remove cage eggs from their supply chains.
