It was presented by Labour leader Andrew Little, finance spokesman Grant Robertson, and Green Party co-leader James Shaw at a business breakfast hosted by law firm Kensington Swan in Auckland, where the audience was made up of business leaders, bankers, economists, academics and NGOs.
The two parties said the new rules would give New Zealanders confidence about how the two parties would work together on economic issues.
But they are also an attempt to reassure voters who are unsure or sceptical about how the Greens could influence Labour's economic agenda.

"If the Greens propose ideas they want that working group to look at, they're welcome to do so.
"But what we're saying is in a Labour-led Government, we're not planning on that policy.
