Hoki / Blue Grenadier

What is hoki / blue grenadier?

Hoki (Macruronus novaezelandiae), also known as blue grenadier, live in the waters around southern Australia and New Zealand 

Hoki flesh is delicate, succulent, and tastes slightly sweet, producing a medium flake once cooked. It is more flavourful than most other white fish because of its higher fat content but is still relatively mild-tasting. Hoki is usually sold as frozen fillets internationally but is also available at fresh seafood counters in New Zealand and Australia.

• They swim deep: Mainly found between 200m and 600m this deep-water species can be found in waters up to 1000m, which is over ten times the height of Big Ben!   
• Hoki have a few names: This fish also has different regional names such as blue hake, blue grenadier, and whiptail. 
• They're carnivores: Hoki is carnivorous with sharp pointed teeth, predating mainly on bioluminescent lanternfish as well as squid and crustaceans. 
• Hoki spawns from June to September: Hoki migrates from dispersed feeding grounds to annual spawning grounds.

Learn more about hoki fishing

Hoki fishing is vulnerable to the effects of climate change on fishing. As waters warm, fish swim to cooler waters and adds to the challenge of fishing.

In 2001, New Zealand hoki was the first large-scale whitefish fishery to achieve MSC certification. The fishery was subsequently re-certified in 2007, 2012 and 2018.

Hoki is managed as two stocks: the eastern stock and the western stock. Hoki is a fast-growing fish, living for 20-25 years and can grow to over a metre in length. It is caught using both pelagic (mid-water) and bottom trawls.

Between 1995 and 2000, the western stock declined due to low recruitment - there were fewer new fish of the required size and age. New improvement action plans on stock rebuilding were therefore introduced. 

Throughout the certification of the hoki fishery, catch limits have been reduced several times to allow the spawning stock to increase. The western stock is considered to be fully rebuilt.

The hoki fishery also works to reduce bycatch of fur seals and have observers on board to check that management is compliant.

Like all major commercial fisheries in New Zealand waters, hoki is managed by the Ministry of Fisheries using a quota management system.

The Deepwater Group, under which the fishery operates, is an amalgamation of EEZ fisheries quota owners. The non-profit group works in partnership with the Ministry to ensure New Zealand gains maximum economic yield from its deepwater fisheries resources, utilising a long term sustainable framework.
