Even so, it says recreational anglers will need to obey the new rules, unfair as they may consider them to be.
The new rules apply to waters out to 200 nautical miles (370.4km) off the east coast from North Cape to Cape Runaway.
They are heralded by the Ministry for Primary Industries as part of a long-term plan to improve New Zealand's most valuable inshore finfish fishery.
The ministry is appealing to anglers to play their part in the fishery's survival with gentle handling and the careful return to the sea of undersized or unwanted fish.

"Simple steps like keeping fish in the water ... returning fish close to the surface of the water and removing hooks gently can all help improve a fish's chance of survival after release."
