A judge has tried to prevent Hone Harawira from prolonging his hearing on the minor charge of failing to comply with a police instruction, which was laid after a protest in Auckland last year.
Harawira, who is representing himself, has called about a dozen witnesses, all of whom were fighting the removal of state houses in the east Auckland suburb of Glen Innes one night last October.
They occupied a property being removed in preparation for redevelopment, while Harawira allegedly locked himself in his car and turned his music up loud, blocking a Housing New Zealand-contracted truck and trailer unit from leaving with the house.
Police told him several times to move but he refused and they eventually smashed a window and arrested him.
He pleaded not guilty and during his defended hearing at Auckland District Court has argued that he did not move the car because his headlights were ensuring the safety of female protesters on the roof of a house.
