Update: 7:52 am – The Winter Energy Payment will be $700 for couples and parents with children at home and $450 for single people.
Monthly payments will be made from May to September, if Labour leads the next government.
Mr Little says around a million people will benefit from the policy, which has been costed at $374 million.
“Around 1600 New Zealanders die each year because of cold housing – that’s four times the road toll,” he said on Monday.
“It’s time for a fresh approach to fix this.”
Mr Little says a recent survey showed four out of 10 people were turning off heaters to avoid high winter power bills.
“That shows there’s a real need for help.”
The Winter Energy Payment is part of Labour’s Families Package that will be unveiled on Tuesday.
