The Greens say the government's large increase in funding to promote mining and drilling is a 19th century economic strategy that will take New Zealand backwards.
The Green Party says that in a bleak budget where most lines have been cut, the government has increased funding of Crown Minerals, the government business unit responsible for promoting mining and drilling in New Zealand, by more than 50%.
"More money promoting mining and drilling means less money invested in smart, green economic development," Green Party energy spokesman Kennedy Graham said.
"This budget shows the priority of John Key's government is to try and make a quick buck, which will ultimately take New Zealand backwards.
"It is a threat not only to our clean, green brand, but also to our children and grandchildren who will suffer the climate consequences of our continued use of fossil fuels."
Graham said New Zealand's future prosperity depends on investment in clean, green technology and sustainable jobs.
