Climate change activists have taken their protest to the steps of Simon Bridges' electorate office in Tauranga.
The National Party leader posted to Facebook that his property had been defaced by members of Extinction Rebellion, a global environmental protest group.
A black oil-like substance has been dribbled across the steps with an Extinction Rebellion symbol visible.
"I respect your right to protest Extinction Rebellion but not when it comes to defacing people's property as you've done to my electorate office overnight," Bridges wrote.
