What tags are used? 150mm long non-invasive serial numbered plastic dart tags manufactured by Hallprint Fish tags in Australia. Tags are placed into the flesh of a fish next to its dorsal fin. When a kingfish is tagged the details are recorded (tag number, length, GPS location etc.) The fish is released. Tagging is carried out quickly so that there is little or no stress to the fish. When the fish is recaptured it is re-measured and details such as location and tag number are recorded again along with any observations. From this information it can be established how far the fish has travelled and how big it has grown over a certain length of time. The information collected is used by scientists & educational institutions.

If you would like to get involved in a tagging program please contact Scott & Sue Tindale at Tindale Marine Research Charitable Trust. Read about that tagging programe here Inshore Tagging programme


Historically fish tagging programs in New Zealand have mainly focused around managing sustainablity of fish stocks for harvest. These programs focused on larger kingfish that swim and live around the coast of the north island of New Zealand and offshore islands. This tagging program was a pilot program that focused on kingfish that venture onto the flats and into skinny water. These fish are a very valuable resource particularily to the travelling fly angler and not much is known about their movements.

The pilot program I started in 2015 has now been taken on by the scientists who provide information to the government agency tasked with managing our fisheries in NZ. Fly fishing has helped illustrate that all kingfish, regardless of size are a valuable resource and can be a real asset to the fishing tourism dollar in NZ. When we tag a king, you can be sure the information gained is put to good use.

"A good gamefish is too valuable to be caught only once. The fish you release today is your gift to another angler tomorrow.".
