Recreational fishing would be allowed, with reduced bag limits, except in a few protected areas.
But commercial fisherman have vowed to fight the plan, with Whangarei Fisherman's Association president Greg Hayes saying there was no scientific evidence to back imposing such a big no-take zone for commercial fishers.
In fact, Mr Hayes said, recreational fishers took far more fish from the proposed area than commercial fishers, with only about 30 commercial boats operating in that area - and not every day.
He said the group would support a small "total no take" zone in an area such as around Rimariki Island, off Helena Bay, or between Tutukaka and Ngunguru, but would oppose any plans to ban commercial fishing from such a large area.
"It's such an absolutely huge area and I'd like to know exactly what Mr Jongejans is trying to protect there.
"Commercial fishermen will tell you that snapper stocks in that area are in great shape and better than they have been for 20 years."
