The species has been very successfully developed given its ease of
propagation, rapid growth, adaptability to a wide range of soil conditions
and its structural properties. The supply volume of this species is growing
rapidly with New Zealand

Heartwood is pale
yellow-brown. Sapwood is wide and not always readily distinguishable from
the heart wood. The texture is fine but uneven. Grain is usually straight
except for a central core of approximately 100mm in diameter which has a
Shrinkage about 3 % radial
and 4.5% tangential. The material is easy to work and nails satisfactorily.
The wide sapwood band is readily treated with preservative chemicals so
lends itself to a number of extrernal application as a treated product. Very commonly
available in both untreated and treated timber in a wide range of sizes and
construction, joinery, flooring, panelling,
plywood, particleboard, fibreboard and paper. In
its treated state it is used for decking, cladding, external trims, poles,
piles, fencing and sleepers.
