The brick and wood interior was decked out with blue ribbons and blue and white balloons.
Vandalised campaign hoardings depicting Prime Minister John Key as Batman and Mr Bridges as Robin took pride of place on the walls.
Mr Bridges admitted to his share of nerves but his faithful never seemed to doubt him or the party - the hubbub was loud and cheerful throughout the night.
"The butterflies and nerves all day have been going. I would have thought by the third time I'd have been a little bit cooler," Mr Bridges told the Bay of Plenty Times after giving his victory speech.
"It's intensely personal because it's an evaluation and a job interview. I'm incredibly grateful to the people for returning me and I pledge to work intensely hard every day for the city."
The crowd cheered loudly as Mr Bridges stood before them to claim his third consecutive victory.
Mr Bridges suspected much of his support was the result of his activity in Tauranga.
"I think I've worked really hard in Tauranga for six years."
Mr Bridges said the huge number of seats National had gained meant there were many more of his peers would become Cabinet ministers and caucus members.
He could not say whether he would continue as Minister for Energy and Resources.
He thanked the supporters who delivered pamphlets, erected and fixed hoardings, manned the office and hit the phones.
Mr Bridges celebrated the victory on Saturday night with wife Natalie and supporters but spent yesterday relaxing with their children Emlyn, 2 and Harry, 7 months, with a bike ride and cafe lunch.
