Observer services

Our observers collect independent information on board commercial fishing vessels about fishing catch and effort, fishing activity, and effects of fishing on the environment. Find out about the information they collect, what you need to do if an observer is on your vessel, and our planned observer days.

What fisheries observers do

Fisheries New Zealand places observers on vessels commercially fishing in New Zealand waters and the high seas, if landing to New Zealand (under international agreements). They independently confirm catch and effort to catch fish and collect a range of information including:

  • data on fish being caught, fish processing and fishing activity
  • information about marine mammal and bird interactions
  • biological information for stock assessment
  • unusual specimens for museums
  • information about vessel safety and employment.

Independent catch and effort data

Observers collect independent data to compare to fishing vessel data. They keep a separate catch and effort logbook, recording:

  • catch calculations and amounts for all species caught
  • details of fishing operations such as:
    • start and finish times
    • positions
    • fishing and bottom depths
    • devices and practices to protect non-targeted species
    • catch data for each tow or set.

Data collected for other agencies

Observers collect information for Fisheries New Zealand as well as for the:

If an observer is on your vessel

If we ask you to take an observer on your fishing vessel, then you must carry one as a condition of your fishing permit. You must provide them with:

  • food
  • accommodation
  • access to the vessel, records, fish, crew, and equipment
  • full access to communication devices on the vessel
  • help to complete their duties.

Observers aren't enforcement officers, but they must record any potential offences they observe.

2019-2020 observer seadays plan

Each year, Fisheries New Zealand and the Department of Conservation plan the number of observer days needed at sea for different fisheries and clients. The 'seadays plan' is for 1 July to 30 June each year.

The following tables show the current number of sea days planned for each fishery and the total delivered up to 20 November 2019.

Observer pre-placement health and safety assessments

Commercial fishing vessels need to pass a health and safety assessment before an observer can board for departure. This will help Fisheries New Zealand meet its obligations under the Health and Safety at Work Act 2015.

Fisheries New Zealand staff will assess a vessel before the observer is deployed. This should give the owner the opportunity to mitigate health and safety issues without it being held in port.

For now, a pre-placement health and safety assessment must always be performed before an observer boards for departure. To reduce the disruption that assessments may cause, Fisheries New Zealand is developing a risk assessment process to determine how often assessments are needed. This will make sure everyone meets their health and safety obligations with the least disruption.

Fisheries New Zealand has developed assessment forms for both inshore and deep water vessels. Fishers should read these to ensure they understand what inspections will involve.
