Protesters gathered outside Wellington's High Court today, as a lawyers' group challenges the Government's climate moves. 

Lawyers for Climate Action alleges the Government's emissions reduction plan doesn't add up - and wants the Court to order it back to the drawing board. 

Executive director Jessica Palairet says this is the first case of its kind in New Zealand. 

"These kinds of challenges have actually happened all around the world. So in the UK, the Government was challenged two times on its plan and had to go back two times and do a better job."
