Fourteen Northland police staff will be volunteering to help in Habitat for Humanity's Metra Big Town Build.
Two teams of seven will take part in the build at Homeworld on Western Hills Drive in Whangarei.
They are among the volunteers who will take 10 days to build the house, starting on Friday.
Once the house has been completed to a lockable state it will be transported to its final location in Kamo.
The police teams, which will be working on November15 and 21, will be a mix of those experienced in the building trade and some who have never set foot on a building site.
