Process heat demand figures are taken from the 2016 MBIE/EECA heat plant database.
For commercial confidentiality reasons, regional totals do not include fuel demand for some large industrial users.
Distribution of planted forest in New Zealand
The North Island has much more dense planted forest coverage than the South Island. The Bay of Plenty region has the most forest coverage.
