Joseph Bergin is a current member of the Devonport-Takapuna Local Board and is also running for a spot on the Auckland Council.
Several candidates in this year's local body elections have only recently become eligible to vote.
Among the Auckland candidates, one used his 21st birthday bash to launch his election campaign earlier this year and another still has to sit her learner driver licence test.
When Joseph Bergin was first elected to the Devonport-Takapuna Local Board, he was in his final year at Rosmini College, where he was deputy head boy.
"It was a little weird. The Auckland Council staff didn't know what to think having this 18-year-old walking around the offices," he said.
Mr Bergin, who is hoping to be re-elected and is also running for a spot on the Auckland Council, for the North Shore ward, used his 21st birthday party to kick off his election campaign.
Mr Randall said it had been a tough ride, at times, particularly because of his age.
The 31-year-old offered some advice to younger candidates. "Think about what you want and what you want to achieve. If you do get in, then work with people, and if you don't get in, don't let it stop you. If you really want to get in, work hard and, eventually, you will."
