Fish Spawning Indicator
Plantation forestry activities must be managed to avoid disturbance of river and lake beds, or wetlands, when fish are spawning. Use the Fish Spawning Indicator to assess the risk.
About the Fish Spawning Indicator
Any forestry activities that would disturb perennial (permanent) river or lake beds, or wetlands, when fish are spawning are not permitted without resource consent. Spawning periods vary depending on the fish species and its location, so we developed the Fish Spawning Indicator to help councils and foresters manage and plan forestry operations.
The Fish Spawning Indicator shows where and when fish that are sensitive to disturbance are spawning. This will make it clear which forestry activities are permitted, and which ones will need consent (if permitted activity conditions are not met). The tool is available online.
Note: The guidance on the use of this information and associated reports is written in relation to the NES-PF context only. The guidance documents should not be used in any other context without guidance from the agencies responsible for the species in question, including the Department of Conservation or the relevant Fish and Game Council.
The database is available
You can download the full Fish Spawning Indicator dataset in several formats (Shapefile, KML, Excel) along with the metadata on the MPI Open Data Portal. The current version of the FSI was released in July 2017. The database provides information for the North and South Islands only – not for New Zealand's offshore islands.
