The Government says a minimum wage of $18.40 would cost 26,000 jobs.
During question time Prime Minister John Key was asked about the new minimum wage of $13.75 and calls for a living wage of $18.40 in Parliament today.
He had to leave Parliament without answering, but tasked labour affairs minister Simon Bridges with responding on his behalf.
Mr Bridges would not say if the new minimum wage of $13.75 was enough for families to live on.
He said there was a range of packages available for people on low wages and New Zealand's minimum wage was one of the highest in the developed world.
