According to a December 29^th article in The Guardian, New Zealand will implement a 2012 decision to ban conventional battery cages.  As of December 2022, ten percent of the national flock was housed in conventional cages, 33 percent in colonies, 29 percent in barns and 28 percent as free-range.  At the time of the original decision made by the National Party Government in 2012, 86 percent of hens were housed in batteries.

The national flock of New Zealand is down to 3.4 million hens compared to 4.2 million in mid-2021.

The Ministry of Agriculture has inspected 26 farms during 2022 to ensure compliance by the January 1^st, 2023 deadline.

From the figures presented, 3.4 million hens would produce 82.8 million dozen annually at an average of 80 percent hen-day production.  Given that the population of New Zealand is 5.1 million, per capita consumption is 194 eggs. According to the Producers Federation of New Zealand, retail sales in 2022 were expected to attain $180 million representing an average unit price for retail packed eggs of $2.17 per dozen.  Export value is negligible at $11 million, presumably to island nations in the South Pacific.
