"Now we're in Government, we think it's important to take the lead on this issue, and to try to counter some of the influence of money in politics," Mr Shaw said.
On Sunday, co-leader hopefuls Marama Davidson and Julie Anne Genter were quizzed by party members as to their aspirations if they were to be successfully elected.
Rather than give speeches, the party members divided into groups to come up with questions for the candidates, based on core party tenets such as consideration of the Treaty of Waitangi in decision making, redistribution of wealth, and social and environmental responsibility.
Both women talked of the importance of involving tangata whenua in all decisions, and the need to further bolster the party's support to get them through the next election.
On the economy and the party's drive to deliver social equality they both talked about the need to think and talk differently about the economy.
"We need to be investing in infrastructure - this is a good time to be borrowing while global interest rates are low," said Ms Genter.
"While this could be tarred as economically irresponsible while we were in Opposition, in Government we can reframe the economic narrative.
"Our job is to bring New Zealanders on board and reframe political priorities away from fiscal to social responsibility."
Ms Davidson said people needed to stop seeing Government spending as bad, and noted that in countries like Denmark and Finland social outcomes were far better than in New Zealand.
"We need to be putting people and the environment at the heart of the economic system."
After the session, both said they thought it was a good process that would give the membership the information they needed to take back to their branches around the country.
They said they would be travelling around the country in the next three weeks to talk at more meetings before their campaign finished on March 25.
The successful candidate would be announced on April 9.
