The code of welfare for dairy cattle has been amended to address behavioural needs and off-paddock systems, says the National Animal Welfare Advisory Committee (NAWAC).
John Hunter, chief executive of Burger King New Zealand, says in partnership with leading egg producer, Zeagold, Burger King will be the first large burger chain to move to 100% free range eggs New Zealand wide.
"Burger King takes its responsibility in maintaining market leading practices on animal welfare, seriously."
This latest initiative from Burger King comes after the company announced the addition of milk to its Kids Meals at prices cheaper than soda options.
In August 2014 Burger King became the first major burger restaurant chain in New Zealand to display the energy content of menu items on menu boards.
