The most commonly used cages for housing layer hens in New
Zealand will be phased out by 2022 under a new code of welfare
issued by the Minister for Primary Industries, David Carter. The
National Animal Welfare Advisory Committee (NAWAC) developed the
new code after reviewing the 2005 code and considering
scientific evidence and submissions from the public, said
committee chair John Hellström. The new code contains minimum
standards and best practices that aim to encourage the highest
standards of animal husbandry, care and handling. The code
covers the full range of hen husbandry topics, including the
provision of food and water, shelter, and protection of health.
The biggest change in the new code is to require that the cages
in use now can no longer be used. From 7 December 2012 the cages
commonly referred to as “battery cages” will no longer be
allowed to be installed, and existing cages will be
progressively removed from use over the next 10 years. Battery
cages house three to five hens and restrict hens
