- What is the wood density of South Pine’s timber?
- Our timber is primarily sourced from the high density region of Nelson which also has the highest average tree age in New Zealand. New Zealand pine exhibits variations in wood density related to the locality in which it is grown, genetic make-up, silvicultural treatment, the part of the tree from which the wood comes and age at harvest. Density is correlated to important qualities such as timber strength, machining and finishing properties. New Zealand pine wood density is well suited for high value re-manufacturing.
- What is New Zealand pine’s strength properties?
- New Zealand pine’s strength and stiffness properties generally cover the range of commonly used structural softwoods.

- Is South Pine’s timber cut from plantation forests?
- Yes. New Zealand is a world leader in plantation forest management and the pine estate is managed on a sustained yield basis. Nelson is New Zealand’s second largest export region for forest/wood products.
- What are the machining properties of New Zealand pine?
- The superior machining properties and its ease of moulding, turning, planing, joining and furniture manufacture are strong features of New Zealand pine.Comprehensive trials conducted at NZFRI, in the United Kingdom and by the University of California have shown that New Zealand pine compares very favourably with softwood species commonly used in Europe, North America and Asia for higher value products.

- Does South Pine kiln dry its timber?
- Yes. South Pine as a “NZ Dri Licencee” prides itself on producing high quality stress free and consistently dried New Zealand Pine. We have 7 kilns: 2 x conventional kilns (80°C – 90°C, 3 to 5 days drying time),1 x high temperature kiln (105°C – 130°C, 12-36 hours), and 3 x medium temperature kilns (80°C – 105°C, 2 to 4 days) 1 x Continuous drying Kiln
- Does South Pine preservative treat our timber?
- When timber is tantalised it is resistant to fungal degrade and insect attack. New Zealand pine’s sapwood is extremely permeable to preservatives, permitting total penetration rarely achieved with other softwood species. South Pine uses Tanalith CCA in H3 (exposed to weather) and H4 (ground contact/landscaping). Products include post, palings, decking, framing etc.
- Does South Pine use anti-sapstain/ bluestain treatment?
- Yes. South Pine uses Hylite Clear (liquid fungicide and anti-sapstain).
- Is New Zealand pine easy to stain?
- Our pine is an extremely versatile wood and and readily accepts the many stains that are available with extremely good penetration and consistency.
- How is the timber transported?
- South Pine’s domestic timber is transported through out New Zealand in full truck and Trailer loads (FTL).
- The majority of South Pine’s export timber is shipped in 40-ft containers and the balance is shipped break-bulk. Transit times range from 1-4 weeks.
- How many m3 fill a 40 ft container?
- Approximately 38 – 42m3, depending on dimensions and lengths required.
- What lengths does South Pines supply?
- South Pine supplies domestic timber in select length packets ranging from 3.6 to 6.0 m dependent on the product.
- South Pine supplies export timber in random length packets from 2.4 to 6.0 m (heavy 4.2 – 6.0 unless agreed otherwise).
- What size timber does South Pine produce?
- Standard thickness produced is 50mm and arising from this South pine produces 25 and 40 mm. The widths vary between grades. Please refer to our South Pine products page.
- What are South Pine’s general terms of payment?
- Irrevocable letter of credit payable on sight of documents or TT payment prior to shipment in US dollars.
- Can South Pine dress or gauge its timber?
- Yes. We produce a range of timbers with different finished, including dressed 4 sides, tongue and groove, decking, rougher headed and gauged structural framing.
- How much timber does South Pine export?
- Over 25% of our production is exported to countries such as China, Indonesia, Malaysia, Vietnam, Thailand and Taiwan.
