"They did an awesome job," he said.
His wife Cinthia Mendes described the fire as "just immense" and there had been no choice but to help.
The Helensville couple had moved a relocatable house on to the section as a holiday home, the flames reaching to within less than a metre of it.
Neighbour Kaye Nairn said she stayed up all night, sending her baby to friends because of the toxic smoke.
It had been a "scary, really scary" night. She had believed she was going to lose her home, and thanked the firefighters profusely for saving it and others.
"I didn't sleep all night," she added. "Everything happened so fast."
She had helped drag hoses to the fire.
"These guys were exhausted, and if I could say anything it would be that we need more volunteers, but I'm proud of myself and other residents for mucking in and helping the brigade and saving our houses," she said.
The blaze was being fought on a 200m front by the time it was brought under control, the Rawene brigade responding to three more calls overnight to deal with flare-ups in pampas, elephant grass and other weeds.
