What is Aquaculture?
Aquaculture (or marine farming) is the breeding and growing of animals and plants in the water. It can take place on land or in ponds or tanks, but most aquaculture in New Zealand occurs in the sea.
The main commercial species farmed in New Zealand are green lipped mussels and pacific oysters. Green lipped mussels are grown on lines suspended from floats on the surface, while Pacific oysters are grown on intertidal racks. Other species farmed include salmon, paua, snapper and kingfish.

Aquaculture in Northland
The only species farmed in the sea in Northland are oysters and mussels . There are approximately 700 hectares of oyster farms scattered throughout Northland's harbours. By comparison, there are only 43 hectares of mussel farms, most of which are just north of Houhora Heads. On land, NIWA has an aquaculture research facility at Ruakaka, Bream Bay.
What’s the Council's role?
The Northland Regional Council is responsible for administering nearly all aspects of marine farming in our region. These include:
- monitoring existing farms;
- ensuring compliance with resource consent conditions;
- granting resource consents for new marine farms; and
- writing the policies and rules determining where new aquaculture can and cannot go.
Monitoring marine farms
We regularly monitor the state of marine farms throughout Northland, helicopters having been found to be the easiest and cheapest way.
We also investigate complaints made about marine farms and the alleged effects on the environment of non-compliance with rules or consents.
