It is not up to Greens co-leaders James Shaw or Marama Davidson whether they decide to form a coalition with National Party at this year's election.
Mr Shaw says membership, not the leadership, decides who they join forces with.
"If we were in the slightly improbable position of being on the cross-bench with an option to either continue with our current partnership with Labour or switch and go into Government with National, then we'd need a package on the table that as better for protecting nature, better for action on climate change and better for reduced inequality in New Zealand."
Meanwhile, changes to central Government Essential Freshwater regulations reflect farmer feedback, says Federated Farmers.
"While we're still working through the detail, the high level policy decisions indicate the government has heeded some of the rural sector concerns" said Federated Farmers environment spokesman Chris Allen.
"What farmer groups seek now is the opportunity for input to ensure the final regulations and National Policy Statement matches the intent of the policies. And if the regulations are shown to be flawed or impractical, the government needs to be open to changing them".
Feds said farmers and rural communities had put a lot of time and effort into providing feedback on the initial proposals, outlining concerns with the practicality and cost, and the lack of recognition of work already under way on-farm.
The thousands of people who turned out at meetings up and down the country, organised by Federated Farmers and industry bodies Beef & Lamb NZ and DairyNZ, showed a level of unprecedented concern.
As a result there had been much needed changes to timeframes, some of the water quality limits and rules around stock exclusion.
"The proposals still have some sharp edges that will bite our farmers and rural communities at a time when we need it least" said Allen.
Given there was no further opportunity to provide input into the national framework, as it will now become law, Federated Farmers said it was focused on ensuring these proposals had an appropriate implementation plan.
"We want to work with the government and regional councils to this end. In particular we want to ensure there are no more amendments to national freshwater objectives so farmers know what they're working towards" said Allen.
"As we've been saying all along, we want regulation that recognises and responds to the good work farmers are doing, and the importance of food production to our communities".
Federated Farmers said that meant supporting farmers to find the high value actions for improving water quality at a farm level in the catchments and hotspots where it was needed, building on the work farmers had been doing around fencing streams and rivers, planting riparian strips, covenanting land with outstanding biodiversity and investing in improved effluent systems.
