"You have four people going absolutley flat out," Mr Pryce said.
Whanganui's time was 1m38secs. The next closest time was two and a half minutes.
"We beat them by 50 seconds, which is a huge amount."
The team had been practising for three months and were "stoked" by their win. They have offered to host the next competition in Whanganui. It will be in April next year, possibly at the racecourse or Cooks Gardens.
Sunday's was a first for this region. Next year they hope to have teams from Rangitikei, Manawatu and Ruapehu as well as Taranaki.
The Whanganui Rural Fire Force has about 15 paid casual and on-call firefighters. They all carry pagers during summer.
When pagers go off they head to their base at the Whanganui Fire Station, pick up their yellow trucks and head out.
