The Green Party launched a campaign recently to stop the proposed construction of the gas-fired power plant in the King Country.
They say it would increase greenhouse gas emissions, causing climate change.
The Green Party is asking Environment Minister Nick Smith to 'call in' the application on the grounds that burning more fossil fuels will affect New Zealand's obligations under the Paris Climate Change Agreement, and then decline Nova's application.
"The National Government needs to show it takes climate change seriously and stop new fossil fuel power plants from being built," said Green Party energy spokesperson Gareth Hughes.
"At this time in history the choice should be easy: investing in clean, renewable energy, not building new power plants that burn dirty fracked gas and cause climate change.
