The European Union has banned standard battery hen cages and New Zealand is following suit.
New Zealand’s replacement will be “enriched” colony cages, which feature improvements like perches and a scratching mat.
The replacement cages are expected to be signed off by Biosecurity Minister David Carter by the middle of the year.
It is estimated the upgrade will cost egg farmers $150 million.
Animal welfare groups, including the SPCA, say it is a waste of time and money.
The egg industry has refused every request by media including numerous attempts by Campbell Live to visit the trial of the colony cage system. But Campbell Live has received undercover footage of the cages.
