About 109,000 hectares of Douglas-fir (NZ Oregon) is grown in New Zealand — mostly in the South lsland. Timber from the species has been widely used in New Zealand, the United States and elsewhere for house weatherboards and framing.
It is highly durable so long as proper weatherproofing systems are used during building design and construction. Indeed, the fact that it can be used untreated for these purposes has made it a sought-after alternative framing timber.
