These graphs from the Hauraki Gulf 2020 State of Our Environment Report show how some New Zealand fish populations are managed very poorly.
You can see that Fisheries New Zealand has no intention managing these ‘stocks’ to the target. Instead they manage populations to the limit where action is required. This is like driving a car at the speed limit the whole time and slamming your brakes on at the corners. Some people may drive like that, but New Zealand should have better attitudes to managing its native marine biodiversity.
