"Mr Pink has stated that he's embarrassed about this incident, it's a backward step and that he was falling back into his old habits."
Pink's last cannabis conviction was in 2015, he said.
Judge Merelina Burnett said Pink liked to "hold himself out as a role model for various groups within the community".
Laybourn replied that his client had taken a stand against P in Ngaruawahia but he was also aware that possession of cannabis was illegal and he wanted the matter dealt with straight away to avoid wasting more police and court time.
The judge ordered Pink pay the fine in full within 28 days. The maximum fine on each charge is $500.
Pink and his Tribal Huk gang are also well known for making sandwiches for hungry school kids in the Waikato, feeding about 1000 children.
Pink became notorious in the small Waikato town after taking vigilante action to rid Ngaruawahia of P, and getting involved in a shoot-out that left his vehicle ridden with bullets.
