David Seymour has pulled out an extreme label for the Green Party - over its mining policy

The Greens say the industry is not safe - and announced it would revoke fast-track permits for coal, hardrock gold, and seabed mining, if in power.

The Act leader denounced them heading into Question Time, today.

He says if you start ripping up consents because you don't like them, you're trashing New Zealand's reputation.

He says the Greens are actually terrorists in that sense.
