The Green Party has announced two new transparency measures.

Co-leader James Shaw says the new measures will apply to Green Party ministers, as well as MPs and staff, to help counter the influence of money in politics.

He says Green Party ministers will soon proactively release their ministerial diaries, to show who they've met with and why.

In addition, Green ministers, MPs and staff will not accept corporate hospitality, such as free tickets to events unrelated to their work.

A hundred of the party faithful have gathered in Napier for the Green Party's summer policy conference.

It's the first time they have got together since last year's election.

Shaw said there would be sessions about what the party has been up to in the past 127 days and what dilemmas it faces.

He said they would look at a series of hypothetical situations, role-play them and ask members what they would do in those situations.

There would also be policy workshops on clean water and how to get to a carbon-neutral economy by 2050.

Co-leader hopefuls Marama Davidson and Julie Anne Genter will this afternoon make pitches about why they should get the job.

The two women vying for the Green Party co-leadership will be making their pitch to members this afternoon.

Shaw says the winner will be announced on April 9.
