Ngongotaha Volunteer Fire Service acting chief Francis Boag said he was extremely proud of his team.
"Clay was the fastest out of our team, taking between 12 and 14 minutes to reach the top. Natasha did really well, too.
"We managed to reach our target - overall we raised more than $1 million for LBC.
"Big praises to all the firefighters and the support of the community, and a big thank you to the organisers for allowing us to take part."
The challenge kicked off at 8am and LBC chief executive Pru Etcheverry said the firefighters were competitive on the climb.
"We loved their enthusiasm and are deeply appreciative of their dedication and support," Ms Etcheverry said.
There was also a special squad of non-firefighters competing in the event, comprising well-known New Zealand celebrities, media personalities and LBC corporate supporters.
These included Seven Sharp presenter Nadine Chalmers-Ross and Sky Sports commentator and former New Zealand netballer Adine Wilson.
