Fisher Wang, at 19, is the youngest person voted on to Rotorua Lakes Council, according to progress results.
Fisher Wang said he was speechless after a "crazy afternoon" learning of his election.
"I'm just really surprised and excited. I'm shaking right now."
Wang is believed to be the youngest councillor to be elected into Rotorua Lakes District Council, after Tania Tapsell, who was elected at age 21.
While he hoped to win a seat, he said he couldn't believe the news and said his family were beyond happy for him as well.
Wang joins Mercia Yates, Sandra Kai Fong and Reynold Macpherson as the district's four new councillors.
Councillors Rob Kent and Mark Gould have missed out. All other incumbent councillors were re-elected.
Progress results have the elected councillors as Tania Tapsell with 8707 votes, Raj Kumar 8640, Sandra Kai Fong 7936, Mercia Yates 6925, Peter Bentley 6630, Merepeka Raukawa Tait 6474, Fisher Wang 6172, Reynold Macpherson 5877, Dave Donaldson 5350 and Trevor Maxwell 5343.
Progress results have Steve Chadwick re-elected as Rotorua mayor.
Chadwick said it was good to see a diverse council.
"It's a very good council and reflective of the diversity in the community. Those challengers who are elected into council are going to learn the complexities of making balanced decisions and that's not a bad thing.
"We hold the majority too and that's important. It's not a bloc it's those that see we've got to keep this district moving."
About 40 to 50 people were at an election party at her home.
She congratulated Mercia Yates, who was present at her home, and Fisher Wang.
"Wang is a young guy with integrity. When he struggled with billboards I contacted him and said get used to politics. It's not a nice game but it's how you handle that.
"How exciting our district has chosen someone who's 19. We're going to be the talk of New Zealand.
"To Mercia well done. It's wonderful you're here for all of us to share. People wanted a positive team and that's what's so affirming. They want to keep the place going ... that's what's been delivered.
"It's a very good council."
Dave Donaldson and Trevor Maxwell are both fewer than 200 votes ahead of the first candidate to miss out, Patricia Hosking. She sits at 5180 votes and that could change once special and late votes are counted.
But Donaldson was confident the votes would not swing out of his favour.
He said he and his wife had cast special votes and special votes had previously been in his favour.
"I look at this and think we've got a positive council ... "I look forward to all 10 councillors making a positive contribution."
The four mayoral candidates were Stephanie (Steve) Chadwick, Dennis Curtis, Rob Kent and Reynold Macpherson.
