Help on the way for NZ‘s timber shortage

The opening of a new wood processing plant in Rotorua in a few weeks will help alleviate New Zealand’s timber shortage, says Red Stag group CEO, Marty Verry.

“The plant will add five per cent to the capacity of the New Zealand wood processing sector,” says Marty.

“That equates to around two thousand dwelling units, or most of the estimated shortfall in current timber supply.”

The factory will produce cross laminated timber, or CLT as it is commonly referred to. CLT is a new ‘mass timber’ construction product being adopted rapidly worldwide.

It is made by gluing successive layers of timber laid crossways over the layer below, to form large panels of three, five or seven layers of timber thick. The rigid engineered timber panels are then precision cut by CNC machines in factory and rapidly assembled on site.

In Red Stag’s case the CLT panels can exceed 16 meters by 4 meters in size, making for very fast construction and few connections.

Kaianga Ora is a major user in New Zealand and use internationally is widespread. Google last week broke ground on its first mass timber building in Silicon Valley using CLT.

“We now have the last of the European technicians out of MIQ and doing the final commissioning of the plant. We’re going to bring forward the opening to May to help the timber shortage,” says Marty.

Costing $50 million, the CLT factory is co-located with the Southern Hemisphere’s largest sawmill, Red Stag, in Rotorua. It will employ forty people initially, rising to double that over time, and is part-funded by a $15 million loan from the Provincial Growth Fund.

Marty doesn’t expect all of the CLT factory’s capacity to be used in residential units though as there is already a waiting list of other projects planning to use it, including retirement villages, student accommodation, office buildings, educational facilities and cultural buildings.

“CLT has a value sweet spot in large-format structures, buildings of three storeys or more, and for mid-floors in terraced housing built to the NZS 3604 standard. Apartment buildings and fast-to-install CLT mid-floors will be our residential focus areas,” says Marty.

Supply of flooring materials such as joists, I-beams and flooring panels has had supply problems in recent months, and Marty expects the building community will be quick to take up CLT mid-floors, which drop into place to provide a finished platform to construct the next level on without delay.

Super-mill flexing

Meanwhile the CLT factory’s sister company, Red Stag Timber is also flexing to help with the timber shortage. The country’s largest sawmill, supplying around 25 per cent of New Zealand’s needs, is pulling back uncommitted supply from export markets and squeezing out more hours and capacity to help keep its ITM, PlaceMakers, Mitre10 and independent clients.

“We plan to bring forward further expansion of both the mill and CLT factory on the back of Carter Holt Harvey’s decision to stop supply to key merchant chains,” says Marty. “There are many in the industry that will want to source from an independently-owned supply chain, rather than relying on product from a competing merchant chain.”
