The central North Island holds New Zealand’s largest concentration of plantation forest, and the Bay of Plenty is where much of it is processed or exported. The sector spans growing, harvesting, transport, processing and export, with quite different businesses at each stage.
The log export question
A substantial proportion of New Zealand’s harvest is exported as raw logs rather than processed domestically. The economics are straightforward: export log prices are set by international demand, and at some price points exporting logs returns more than processing them.
That produces a structural tension. Domestic processors compete for the same logs against exporters, and when export prices are strong, processors face input cost pressure or supply difficulty.
For processing businesses this is the defining commercial risk, and it is not manageable through efficiency alone. Supply agreements, forest ownership or integration are the levers that exist.
Harvest is the most dangerous work in the sector
Forestry carries one of the highest work-related fatality rates of any New Zealand industry. The risks concentrate in tree felling, breaking out, and machinery operation on steep terrain.
The controls that work follow the hierarchy:
- Mechanisation — removing people from under trees and off steep slopes entirely. Mechanised felling and steep-slope harvesting technology has changed the risk profile substantially where it is used.
- Exclusion zones rigorously applied, with no person under a suspended load or in the felling zone.
- Communication systems that work in terrain and weather.
- Competence, verified rather than assumed, with training records.
- Fatigue management, since crews work long days in physically demanding conditions.
Overlapping duties apply throughout the chain. Forest owners, managers and contracting crews all hold duties, and the owner cannot contract out of responsibility for work it influences — including through the rates and timeframes it sets. Rates that only work if a crew cuts corners are the owner’s problem.
Transport
Log transport is heavy, high-centre-of-gravity work on rural roads, and load securing is critical. Operators carry the full transport compliance load — work time and logbooks, certificate of fitness, road user charges at the correct rate for the configuration, and driver licensing.
Work time includes loading, unloading and waiting, not just driving. Schedules built to the limit of driving hours leave no room for the rest, and a schedule that cannot be completed legally is the operator’s problem rather than the driver’s.
The ETS layer
Post-1989 forest land can be registered in the Emissions Trading Scheme to earn units as trees grow, with a symmetrical obligation to surrender units on harvest.
Points that catch people out:
- Harvest liabilities can be substantial and arrive when cash position depends on timber price rather than carbon price.
- Averaging accounting changes the profile of what is earned and owed compared with the older stock-change approach.
- Registered land carries obligations that follow the land, affecting sale value and how a buyer views it.
- Planting decisions made purely on a carbon price are exposed to a market that policy settings can move sharply.
This is a long-term commitment deserving proper advice rather than enthusiasm.
Processing and market requirements
Wood processing businesses face the same requirements as other manufacturers — PECPR obligations for pressure equipment and boilers, hazardous substances for treatment chemicals, dust extraction for wood dust which is a recognised carcinogen, and noise management.
Wood dust in particular deserves attention. It causes respiratory disease and nasal cancer with long latency, and on-tool or fixed extraction is the effective control rather than respiratory protection alone.
