Todd Muller pledges to honour his late father after being reappointed Bay of Plenty MP.
It was an emotional electoral victory for Mr Muller when he arrived exhausted but alert at the Omanu Bowling Club on Saturday.
"It has been really intense . . . There's not much left in the tank."
By the end of Saturday night, Mr Muller received 22,688 votes. Labour candidate Angela Warren-Clark received 9547 and NZ First's Lester Gray received 3641.
Mr Muller was celebrating before 9pm, telling the crowd of about 150 becoming an MP was his dream job.
"When I was 10 years old I wanted to be president of the United States, but this is way better."
Mr Muller was greeted with huge bursts of applause.
"I've become who I am because of this community. You are very much part of my family as we move forward over the next few years. Whatever role I get asked to do as part of National . . . you can be sure I will give it everything.
"I will continue to give everything I have to ensure your wishes are heard and importantly, I'll walk your journey with you," he said.
Mr Muller ended his speech by paying tribute to his parents, including his late father Mike Muller.
"I will do everything I can to ensure his memory is preserved through the community and honoured in this city."
Mr Muller was saddened by the loss of Maori Party MP Te Ururoa Flavell who was "a man of great mana" and it was "a real shame" he would not be returning to Parliament.
Mr Muller said he understood why New Zealand First leader Winston Peters was taking time to go through his options but was confident Mr Peters would side with National.
"I would be surprised after it all settles if he does anything other than support the party with the most votes."
Former Western Bay of Plenty Mayor Ross Paterson said Mr Muller thoroughly earned the win.
"Todd's got empathy. He's got the passion, that desire to be in here and do the best he can. I give him full credit for that. The past three years he's done a lot."
Supporter Dave Barker was a "true blue" supporter and had faith the community would be well served.
National Bay of Plenty electoral chairman Sean Newland said Mr Muller was someone who brought people together.
* Mike Muller died suddenly earlier this month. He was a pioneer and respected leader in the kiwifruit industry.
