Wanganui mayor Annette Main is disappointed her youngest councillor was arrested for possessing cannabis but says he must have his day in court.
Ms Main said Jack Bullock contacted her on Friday night about his arrest earlier that day, although she said she had heard about it beforehand.
"I can't take any view of responsibility about his role as a councillor - that's up to Jack," Ms Main said. "It is disappointing that this is happening."
She said under the Local Government Act an elected member was disqualified from their office if they were convicted of an offence punishable by a term of imprisonment of two years or more, but the charge Bullock faced had a maximum penalty of three months' imprisonment and/or a $500 fine.
"It's up to Jack to have a talk to me about how he sees his future. This doesn't affect his legal ability to be a district councillor - it's entirely up to him."
