Tenco is one of New Zealand’s largest exporters of forest products. We have built to this position since 1991 when the company was set up to export lumber to growing Asian export markets. Experience and reputation count; from small beginnings Tenco has become the largest independent exporter of New Zealand lumber and New Zealand’s 4th largest log exporter. Tenco has a regular shipping program of their own log vessels and in combination with these and other ships currently calls at 7 New Zealand ports (5 North Island and 2 South Island).
Tenco buys standing forests. Tenco currently has a number of forests which they purchased at harvestable age to log over a number of years for export and domestic markets. Tenco also regularly buys smaller tracts of forest to harvest immediately or immature forests to hold until harvest time. Tenco is interested in broadening the base of owners from whom it purchases forests and stands of trees. A deal with Tenco is a certain transaction. The owner and Tenco will agree on a value of the tree crop and then Tenco will pay this amount to the owner either in a lump sum amount or on rate per volume unit out-turn from the forest depending on the nature of the tree crop.
Tenco knows there are a lot of farmers who have trees that are close or ready to harvest and will be asking themselves how they should proceed with the sale of their trees. For some farmers the kind of certain transaction with money in the bank could well be appealing. Tenco is actively interested in buying harvestable forests or trees from areas including all the North Island (except the Gisborne and East Coast districts) and Nelson & Marlborough in the South Island .
If you own a forest in this area (16 years and older) and are ready to enter into this kind of agreement Tenco is interested to develop something with you.

Eucalyptus sphaerocarpa, my favourite durable timber species
Saturday, December 20, 2014
Eucalyptus sphaerocarpa is a class 1 durable eucalypt species that I introduced into New Zealand in the mid-1990's. I was looking for a highly durable species from the monocalyptus group of eucalypts, which have shown to have good levels of resistence to insects in New Zealand.
E. sphaerocarpa is a large tree from the Blackdown tablelands in Southern Queensland and grows at about 1000 m altitude. It's called Blackdown stringybark, although actually an ash eucalypt rather than a true stringybark. The timber is highly prized in this area. Mike Wilcox, renowned botanist and eucalypt enthusiast, saw the species in its native habitat and described them to me as "huge magnificent trees, a sight to behold".
So why do I like it so much? It is disease and pest resistent, grows extremely straight and has a very high content of durable heartwood. What more could I ask for... the "silver bullet" from over 20 years of durable eucalypt species trialwork.
Is there a market for ground durable untreated posts and poles in New Zealand?
Is it viable to be production thinning 10 year old trees for naturally durable posts, then growing the remaining trees to 25 years for a high quality class 1 durable hardwood decking product that will last 40+ years in service?
Can we grow durable eucalypts with just standard practice lift pruning and thinning... without any form pruning?
I beleive yes to all questions above. However, we need the right species. In my view the only species that might fit the bill are E. cladocalyx and E. sphaerocarpa. Sugar gum (E. cladocalyx) is a woodland species and has a very open crown. Great for dryland climates where we wouldn't expect much in terms of sawlog volume per hectare. Species with good crown density like E. microcorys (tallowwood) and E. sphaerocarpa can be held at a high final crop stocking and still produce good diameters, thus a high volume per hectare at harvest. Siting tallowwood isn't so easy... wonderful class 1 durable timber but the species has an unstable crown that smashes in high winds, and the species is very frost tender.
What about siting E. sphaerocarpa? My trees were planted on a windy ridgetop in Northland, on low fertility clay soil. They have thrived. Not sure about frost hardiness but I'm working on it and have planted trees in a range of localities throughout New Zealand. The expectation is for medium frost hardiness. Anybody interested in planting this species should get in touch with the NZFFA Eucalyptus Action Group, we are looking for volunteer sites and growers willing to trial durable stringybark eucalypts.
These trees were planted at final crop stocking and were not thinned, demonstrating the good form and potential of the species for deployment into productive forestry plantations.

Great work Dean.
I don't think it is acceptable in the long term to be using toxic treatments to create a durable timber product for above and below ground use.
