National Party leader Bill English has made a few tweaks to portfolios, as the party heads into Opposition.

Most of National's front bench have retained their existing portfolios, as leader Bill English prepares the party for Opposition.

The party plans to nominate senior MP Anne Tolley to the role of deputy speaker however, and up and coming MP Chris Bishop has been handed the weighty police portfolio.

Among other changes to National's frontbench, sees workplace relations handed to Amy Adams who retains Justice - she will directly mark her opposite Justice Minister Andrew Little.

And Nick Smith - former a former Environment Minister and Building and Construction Minister - moves to Forestry and Aquaculture.

Leader Bill English holds only security, while Chris Finlayson remains the party's spokesman for GCSB and SIS. It will mean English and Finlayson will likely sit on the Security and Intelligence Committee.

MP Simon O'Connor has been handed Corrections, a portfolio that has historically been a good area to land political blows.

Senior MPs Gerry Brownlee, Jonathan Coleman and Simon Bridges all largely retain their old portfolios in Foreign Affairs, Health and Economic and Regional Development.

However, Transport has been passed on from Bridges to Judith Collins and Deputy leader Paula Bennett has passed on Climate Change to Todd Muller so she can focus on Children, Women and Social Investment.

"New Zealand is doing well, with low unemployment, thousands of jobs being created every month, strong public services and New Zealanders getting ahead," English said.

"That's a direct result of the hard work and dedication of New Zealanders who have operated confidently with the support of a clear and consistent economic plan and a government focused on achieving measurable results."

National would be pushing the Government to retain what gains had been made.

English's portfolio announcement was as much about marking opposites, as it was about pointing out perceived gaps in Labour's lineup.

Nathan Guy remains spokesman for Primary Industries, despite the new Government's intention to divide the ministry, and Bennett remains the spokeswoman for social investment - English's flagship policy during his nine years in Government.

"We are the largest Opposition Party New Zealand has ever seen, and the largest party in Parliament. We will ensure we make those numbers count," English said.

"I have ensured we make the most of the experience and knowledge of our former ministers, while also utilising the talents of our large caucus who are passionate about New Zealand's future.

"All but the latest intake of MPs have been allocated portfolios. Those MPs will be given time to understand Parliamentary processes and work alongside our spokespeople, and be allocated portfolios in due course."

National would be a "strong and loyal Opposition".

"We are ambitious for New Zealand – and we remain committed to building a stronger, more confident and more prosperous nation.
