The Finance Minister believes we won't be seeing another capital gains tax proposal anytime soon.

Jacinda Ardern has ditched the tax and pledged Labour will no longer campaign for it under her leadership.

Grant Robertson told Mike Yardley there will be no CGT talk from the government for a while.

"The PM has made it clear for the future while she's the leader of the party, it won't be happening.

"I think the Prime Minister is doing a great job and there won't be any other leader of our party for a long time."

Robertson says they didn't have the numbers to implement the tax and their focus will move onto other priorities.

"What the Prime Minister said was, having campaigned in 2011, 2014 and 2017 on this it was time to accept that there wasn't a mandate there to pursue it.

"While we may believe in a capital gains tax, the majority of New Zealanders obviously don't, so we are going to be moving on."
