“More workers building houses on-site is not enough to really lift housing supply,” John Stulen, from Innovatek said.

“Only new high volume wood panel plants will do that in a big way, which is exactly what New Zealand needs. It simply has to happen.

“XLAM’s cross laminated timber (CLT) plant in Nelson and Stanley Group’s modular building factory in Matamata have delivered some added capacity, but there is room for far more supply to meet demand.

“In Australia, developers and large builders have already boosted their industry by adding more wood panelisation plants. It is a welcome sign for ramping up the supply of new affordable housing.

“We need at least one or two more large wood panel factories using new ultra-modern manufacturing technologies to ramp up single family and multi-residential homes in New Zealand.”
