Fletcher Building has shown off a row of five terrace homes constructed in as many days and claim this could be a remedy to the the country's housing demand.
Fletcher's prefabricated method means it takes around one to four days to weatherproof a home compared to 50 days for a standard built duplex home.
The trial is a proof of concept for the construction giant's factory which will open next year, producing around 500 prefabricated houses annually.
Chief executive Steve Evans said, "we wanted to make sure that we could do it for a variety of homes."
"We've moved from a cottage industry to a production line industry," said Auckland mayor Phil Goff.
Once the basic modules are up, the homes can be finished off in six weeks, that's so all the interiors and exterior claddings can be personalised, said the company.
For now the cost of construction is about the same as conventional homes.
"What I would hope in time is that as you get scale, then the pricing should come down and that's certainly our aspiration," said Mr Evans.
"We need 14,000, 15,000 houses a year. We're struggling to do that. with panelisation, we can do it quicker. we get better quality assurance." said Mr Goff.
The company plans to set up a factory in South Auckland, the first panels coming off the line by mid next year.
The aim is to build around 500 homes a year, with the KiwiBuild market in mind.
