Animal welfare activists are meeting in Wellington today in support of a bill to outlaw the use of sow crates and battery farming.
Green MP Sue Kedgley's Animal Welfare Amendment Bill is designed to phase-out restrictive farming practices.
The use of sow crates at pig farms hit the headlines last year, after a documentary showed graphic images of the farming technique being used at a Levin piggery.
SAFE's Hans Kriek says such practices are illegal.
“The New Zealand animal welfare act requires that all animals must be able to express their normal behaviour, and clearly by keeping a pig in a crate that animal can’t express her normal behaviour,” he says.
Mr Kriek says the public is becoming much more aware of animal welfare issues.
