The forestry sector is important to Otago's economy. However, forestry can harm our environment, especially water quality.
pages linking to the deleted section:
There is over 125,000 ha of plantation forestry which supports forestry personnel or contractors, seed and nursery suppliers, downstream sawmilling and manufacturing industries plus the export ports at Port Chalmers and Bluff. A majorityof this area is in pine plantations.
The forest industry consists of large companies such as Ernslaw One, Wenita, City Forests , Rayonier Matariki Forests, and Port Blakely plus numerous smaller owners and farmers who have forestry blocks within their farms.
As well as contributing to the Otago economy, Forestry has been viewed as having a positive effect on the environment by capturing carbon, reducing erosion on hill country as well as having moderating effects on water flows and providing amenity and biodiversity values.
However, all forests must be well-managed to ensure any adverse effects on the environment are managed. For example, assessing wilding conifer risk, establishing setbacks from roads, dwellings and waterways, and managing harvests. Harvesting presents challenges such as sediment affecting water quality from clear felling and the roading networks created.
It is important to understand how a forest and associated forestry activities are defined, as these will determine which rules and regulations apply. The following definitions meet the criteria of the NES-CF Regulations.
Commercial/Plantation forestry refers to any forest that has been deliberately established for commercial purposes which has been or will be harvested or replanted. This applies to all continuous forest cover of forest species larger than 1 ha in area and includes all associated forestry infrastructure.
It does not include:
An exotic continuous-cover forest is one that’s deliberately established for commercial purposes. It is at least one hectare of continuous forest cover of exotic forest species that has been planted and:
It does not include:
Exotic continuous-cover forestry is subject to all of the regulations that apply to plantation forestry. Indigenous continuous-cover forestry is not subject to the regulations.
Term | Definition |
---|---|
Afforestation | Means planting and growing commercial forestry trees on land where there is no commercial forestry and where commercial forestry harvesting has not occurred within the last 5 years. It does not include vegetation clearance from the land before planting. |
Earthworks | Means disturbance of the surface of the land by the movement, deposition, or removal of earth (or any other matter constituting the land, such as soil, clay, sand, or rock) in relation to commercial forestry, including:
|
Forestry Quarrying | Means the extraction of rock, sand, or gravel for the formation of forestry roads and construction of other commercial forestry infrastructure, including landings, river crossing approaches, abutments, and forestry tracks. This includes the extraction of alluvial gravels outside the bed of a river, extraction of minerals from borrow pits, and the processing and stockpiling of material at the forest quarry site. It does not include earthworks, mechanical land preparation, or gravel extraction from the bed of a river, lake, or other water body. This applies to quarrying located within a commercial forest, or on adjacent land owned or managed by the owner of the commercial forest. |
Harvesting | Means felling trees, extracting trees, thinning tree stems and extraction for sale or use (production thinning), processing trees into logs, or loading logs onto trucks for delivery to processing plants. It does not include milling and processing of timber, or clearance of vegetation that is not commercial forest trees. |
Replanting | Means the planting and growing of commercial forestry trees on land less than 5 years after commercial forestry harvesting has occurred. |
River Crossing | Means a structure that is required for the operation of a commercial forest and provides for vehicles or machinery to cross over a water body. This includes a ford, an apron and other structures and materials necessary to complete a river crossing. It does not include a stormwater culvert or a culvert under a forestry road or forestry track. |
The National Environmental Standards for Plantation Forestry (NES-PF) came into effect on 1 May 2018. This was amended to the National Environmental Standard for Commercial Forestry (NES-CF) on 3 November 2023, adding exotic continuous-cover forests (carbon forests) to its scope.
The Regional Water Plan also applies in some instances where a regional rule is more stringent than a national rule (the NES-CF), listed within Schedule 17. These stringent rules relate to sediment discharges and bed disturbance to protect threatened indigenous fish (i.e galaxiid species), many of which are found only in Otago.
If the intended forestry activity does not meet the criteria of ‘commercial forestry’ or ‘exotic continuous-cover forestry’ (i.e the harvesting of wilding pines), NES-CF regulations do not apply. However, existing district and regional plan rules will apply to the activities and effects outside the scope of the NES-CF. For further assistance, refer to the flowchart.
The NES-CF regulations aims to:
These regulations cover eight commercial forestry activities:
Before some of these activities can take place, notice must be provided to regional council (and in some cases district council). Notifiable activities are defined above within ‘Forestry Definitions.’ Some activities may also require the submission of additional information, such as ‘Wilding Tree Risk’ calculations.
A management plan is required for certain activities (indicated with an asterisk above) before commencing work. These plans must be in accordance with schedules 3–6 of the NES-CF, depending on what activity you are undertaking.
MPI have developed several risk assessment tools to assist in planning activities. These are found within schedule 2 of the NES-CF, including:
Most forestry activities are permitted by the NES-CF so long as foresters meet specific conditions designed to protect the environment. If foresters can’t meet these conditions, they need to apply for a resource consent.
The Regional Water Plan holds more stringent sediment discharge rules to the NES-CF and requires that you obtain a resource consent for any river bed disturbance activity (excluding river crossings), such as cable hauling through ephemeral waterways. If foresters can’t meet these conditions, they need to apply for a resource consent.

Although harvesting only has a small impact over the life of a forest, its short-term impact can damage the environment and breach Water Plan and NES-CF rules.

The Ministry for Primary Industries (MPI) has developed resources to guide forestry activities. Most of the guidance from the older NES–PF is still relevant. Each activity guide explains the relevant NES-PF regulations, including:
You can find more guidance on the MPI “Guidance for forestry activities" page here for all forestry activities.
The New Zealand Forest Owners Association (NZFOA) also have resources available on Best Practice Guidelines (BPGs) and road engineering for commercial forestry operators. These resources can be found here.
Your own forestry industry can be of help too.

Our Water Plan and the National Environmental Standard for Commercial Forestry (NES-CF) are documents that regulate forestry activities in Otago, to protect our freshwater resources and ecology.
Water is the first priority of the Otago Regional Council. Our Regional plan and Land & Water Regional plan are two documents that we use to help develop rules and regulations which will help communities protect our water for generations to come.
