The brigade has about 15 volunteers, with just eight attending most calls, but a full complement would be 22.
There were advantages to becoming a volunteer firefighter, Thornton said, especially for people new to an area.
"It's giving something back to the community and you meet some great people, guys and girls."
Daytime crewing was particularly difficult for the brigade, Thornton said, with many people who live locally working outside Maungaturoto.
Volunteers need to live within 5km of the fire station, and those who could respond to daytime callouts were often shift workers.
The Maungaturoto brigade has recently lost several daytime crew members who were shift workers at the Marsden Point oil refinery before its shutdown, Thornton said.
There is an initial one-week training course to become a volunteer firefighter, however that time is paid.
The Maungaturoto team respond to rescue incidents, such as car crashes, as well as fires, but the rescue course firefighters are encouraged to take is run over a weekend.
Thornton said traumatic incidents are only a very small part of the job, however it is worth it to help the community and the fire service has "brilliant" support.
"When you do something for someone and you see the expressions on their faces after you get them out of a car they've been trapped in, that's all I need."
