Today's Parliamentary vote on a climate change emergency is likely to go down party lines.

Prime Minister Jacinda Ardern will introduce a motion to Parliament to declare a emergency, similar to those passed by many councils around New Zealand and governments around the world.

MPs will debate the issue from about three o'clock this afternoon.

National leader Judith Collins told Kate Hawkesby her MPs will oppose the motion.

"It’s pretty easy to declare a climate emergency, but if there’s no plan in place, it just ends up being a virtue signal from the government."

Judith Collins also doesn't support on site pill testing at festivals - even though she knows her opinion is unpopular.

A 2019 Colmar Brunton poll shows 75 per cent of people support some form of legal pill testing. 

National's youth wing also supports the move.

Collins says we need to look further than polls before bringing in new laws.

“If politicians only take a stance on things based on a public poll, maybe they shouldn't be in politics. “
