New Zealand Radiata Pine
New Zealand pine is a light coloured, medium density softwood with a moderately even texture that produces sawn lumber with excellent working properties.
Sawn New Zealand timber dries easily and can be kiln dried rapidly from green. The wood can be readily treated with preservative to achieve all desired durability levels.
Through good silviculture management, New Zealand pine logs come in a range of qualities capable of yielding lumber grades to meet almost any requirement.
For finishing and furniture uses, can either be clear of knots or contain minor blemishes and tight knots. These grades include:
- Clear Timber: Free of knots and blemishes, used for high-quality joinery, furniture and mouldings.
- Cuttings Grades: For reprocessing to produce shorter clear lengths with excellent machining and gluing properties. These grades contain large knots and blemishes that are removed by cross-cutting and ripping. The resulting clear components are often finger-jointed and edge glued to produce mouldings and furniture.

Structural Grades (Framing Grades)
Used primarily for construction where strength and stiffness are important. The main factors influencing a structural grade are the size and location of knots. Grade limit such defects to meet specified strength requirements.
Used in packaging for various products such as pallets, cable drums and concrete formwork. Grades contain a range of knot sizes compatible with final use.
Industrial grades are also produced for export including thin board and a range of other grades to buyer specifications.
New Zealand timber producers are able to grade to most customer requirements. Common export grades include:
- Australia: AS2858 F5 and F7 structural grades (visual) treated and untreated AS1748 MGP grades (machine stress graded)
- United States: Western Wood Products Association random width lumber specifications including mouldings and better, shop and factory grades.
- Japan: JAS structural grade specifications(which also include glue laminated and plywood grades)
- China and Vietnam: NZS3631 cuttings grades and also buyer specified grades
Common Timber Sizes
The standard sizes produced by New Zealand sawmills are;
- Width: 25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275 and 300mm
- Thickness: 25, 40, 50, 75 and 100mm
- Length: 1.8 to 6.0m in increments of 0.3m
These are rough sawn (not planed) dried sizes. Preservative Treatments Effective preservation treatments have been developed to ensure New Zealand pine has excellent performance across a broad range of applications. New Zealand has developed a world leading wood preservation industry and has rigorous codes of practice and the industry has been audited to these for over by Woodmark (hyperlink to the woodmark site). Woodmark is the leading quality assurance programme for preservative treated timber.
In New Zealand, round wood (posts and poles), sawn timber and plywood are treated to six different hazard class levels. Preservative treatment requirements are generally equivalent to or exceed those of other countries that have formal wood preservation standards.
