Labour taking credit for National's TPP agreement - Bill English

With the Trans-Pacific Partnership deal edging towards the line, National Party leader Bill English says Labour is trying to claim his party's hard work.

"I think there's been a bit of exaggeration about what's been achieved in the last week or so," the opposition leader told The AM Show.

"There's been a lot of work in the last 12 months.

"Once the US left, there were significant changes that were negotiated among the other countries. I think there [have] been a few tweaks in the last week or so."

The Green Party still opposes the TPP and will vote against the rebranded version when it comes before Parliament - meaning Labour will need to rely on support from National for the agreement to come into force.

Mr English says they will give that support.

"We worked hard on the TPP. It appears that the agreement may get over the line, although there's still some way to go.

The Greens - and New Zealand First - have long opposed the TPP, with the most-raised issue being the potential use of ISDS mechanisms. They allow companies to sue a Government if they think their rights have been violated under the treaty.

But Mr English says the agreement is "good for New Zealand".

"The three governing parties have all been against the TPP at different times, including the Labour Party, but I think they can see the reality is they have to get this through if they possibly can, and we're more than happy to lend support to something that would be so good for New Zealand and particularly the regions.

"This will have a bigger impact in the regions than any government fund."

Mr English says he hopes Ms Ardern does whatever it takes to get the deal over the line.
