The Ohakune brigade also helped fight the fire, and Whanganui area commander Bernie Rush was also on scene.
Mr Compton said the building was left unusable with "significant damage".
The fire reignited just before 7.30pm, and the brigades were called out again to deal with it.
Mr Rush said fire investigators were on the scene and more would be known about the cause later on Wednesday.
He said no-one was in the building at the time.
The fire took about 30 minutes to put out initially. The old wooden building, used as clubrooms he thought, was three years off its centenary.
"It was so extensively damaged it was difficult to tell last night where it started" Mr Rush said.
