Winston Peters says it will take time, but people will eventually see the good behind the party's environmental policies.
The NZ First leaders says he's still trying to get his head around National's decision to put more than $14 billion towards the Paris Agreement over the next decade, because the country needs to focus on fixing its own problems first.
"When this campaign's over we will have shown enough people out there who are concerned about the environment about the one party that has a water policy, that has an environmental policy, and how we're going to fix the country up ourselves."
The Greens, also hosting an AGM this weekend, have consistently criticised the Government over what they call a lack of ambition to combat climate change.
The party on Saturday announced a $110 million fund to create a carbon-free economy by 2050 and thousands of regional jobs along the way. Additional funding would come through establishing a "fair price on carbon".
Co-leader James Shaw says National has its priorities wrong.
"National continues to build new motorways, rather than new rail lines, to subsidise the expansion of dairy and deep-sea oil drilling. And now they want to build a coal mine on a kiwi habitat on conservation land."
The Greens want to squeeze as much money as they can from the oil industry to help fund climate change projects. Mr Shaw says the oil industry will face a hammering.
"We'll pay for this, at least in the short-term, by raising oil royalties from 46 percent to the international average of 70 percent."
Mr Shaw also slammed the Government for spending money on overseas anti-pollution projects instead of putting the money towards our own problems, labelling it reckless and criminal.
"Over the next 10 years, New Zealand will send $1 billion a year to other countries to build their low-carbon economies and competitive advantages, and not our own," he told supporters.
"The Green Party wants to invest that money here in New Zealand."
