Offsetting deforestation of forest land
You can apply to offset your deforestation of pre-1990 forest land by establishing an equivalent forest. If MPI approves your application, you may not need to pay carbon units for the deforestation. Find out how to apply for forest offsetting, and what criteria the offset forest must meet. Offsetting will also be available for certain types of post–1989 forest from 2023.
Pre-1990 forest offsetting criteria
You can deforest pre-1990 forest without having to pay units by creating an equivalent forest (an offset forest) elsewhere. This offset forest must be approved by MPI before deforestation has occurred. The proposed offset forest must:
- be at least the same size as the area of land being deforested
- be made up of an area or areas that are at least 1 hectare in size, with an average width of at least 30 metres
- comply with section 186B of the Climate Change Response Act.
Climate Change Response Act 2002 – Section 186B – NZ Legislation
MPI must also be satisfied that the offset forest is likely to:
- contain the same amount of carbon as was in the pre-1990 forest land at the time of clearing, within the usual rotation period of the forest species of the pre-1990 forest land (carbon equivalence), and
- become forest land before the pre-1990 forest land is deforested.
Our fact sheet tells you more about forest land offsetting and your obligations.

Post-1989 forest offsetting
Offsetting will be available for post-1989 forests using averaging from 2023.
Applying for forest land offsetting
You'll need to print, complete and post us the pre-1990 forest offsetting application, along with:
- your carbon equivalency calculation (using the look-up tables)
- a map of the offset forest land and pre-1990 forest land in shapefiles (an electronic file type used in digital mapping)
- the proposed planting details.

Calculating carbon equivalence
The offset forest must store the same amount of carbon as the pre-1990 forest land within the usual rotation period for the forest type. This is known as carbon equivalence. You can calculate the area of offset forest that you will need for carbon equivalence using the usual rotation periods and forest look-up tables.
Usual rotation periods
Forest type | Description | Usual rotation period (years) |
---|---|---|
Pinus radiata | Predominant species is Pinus radiata | 28 |
Douglas fir | Predominant species is Douglas fir | 40 |
Exotic softwood | Predominant species is exotic softwood | 45 |
Exotic hardwood (pulp logs) | Forest grown on short rotation for producing pulp logs | 15 |
Exotic hardwood (saw logs) | Forest is grown for saw logs | 30 |
Follow these steps:
- Calculate the emissions from clearing your pre-1990 forest land (at the age of clearing) using the pre-1990 forest land look-up tables.
- Find the usual rotation period for forest species of the pre-1990 forest land in the table above.
- Find the carbon associated with the offset forest at the usual rotation age (from step 2) using the post-1989 forest land look-up tables.
- Calculate the area of offsetting forest land that you will need by dividing the emissions from the original forest (total from step 1) by the carbon stock that the offset forest would store in the usual rotation period (total from 3). This tells you how many hectares your offset forest needs to be to store the same amount of carbon as the original forest.
- Check that the offset forest is at least the same size as the original pre-1990 forest land.

Offsetting Declaration form
Once your application is approved, the offsetting forest land must become forest land before the pre-1990 forest land that is offset is deforested. A person who owns pre-1990 forest land must submit an Offsetting Declaration form once the offsetting forest land becomes forest land.

Do you need to complete a deforestation emissions return?
If your pre-1990 offsetting application has been approved, you don't need to:
- notify us when you deforest the area
- complete an emissions return for the deforested area.
