Australian Green Party leader Bob Brown has travelled to New Zealand to support the Green Party here.
Senator Brown said it is important to have strong Green political representation on both sides of the Tasman.
He said conventional thinking is that Green parties do not do well during times of economic hardship, but the opposite is happening.
"People do think through their children, they're concerned that we hand them on a better world, and if you can do that in a way which is going to create jobs and stimulate the economy they'll go for it - and that's what the Greens are about."
Mr Brown said the public sees Green politicians as having more long-term vision than those in other parties, and that is becoming clear from a global movement to green politics.
