Use the SeaSpotter App
The best way to report your marine mammal sightings is to download the SeaSpotter app:
- on Google Play
- on Apple's App Store
- or search for 'SeaSpotter' by MAUI63.
The SeaSpotter app is a joint initiative between DOC, WWF, Christchurch City Council, MPI, MAUI63, and Microsoft.
Data submitted to the app is logged in an open-source database to be used by government staff and researchers. For more information, visit the SeaSpotter website.
Your privacy on the SeaSpotter app
You can report your sighting anonymously using the app. But if you make an account using your name and email address you can view and track your sightings and support marine scientists.
Your personal details may be used to follow up on your sighting by government staff or researchers. The app also requires access to phone location data.

What happens with your report
Sightings reported directly to the Department or to the SeaSpotter app are recorded in a DOC database of marine mammal sightings from all around New Zealand.
This information will help us determine things like population sizes, breeding rates and movement patterns. This helps us to look after them.
Why reporting helps
New Zealand has earned its reputation as the marine mammal capital of the world because of its profusion of marine mammals. DOC is responsible for the protection, conservation and management of all marine mammals.
To understand more about marine mammals in our waters we need more information about them. Sightings help us to do this.
