An incoming marine protection network off New Zealand's southern coast could lead to crowded fishing spots and make some businesses unviable, a commercial fishing representative says.
However, members of the scientific and tourism sectors say it does not go far enough to protect marine life.
At the weekend the Government tagged 1267sqkm from Timaru to Waipapa Point, in Southland, as a reserve network.
It is the larger of two proposals created by the South-East Marine Protection Forum early last year.
It includes six marine reserves which ban commercial and recreational fishing and five "type two marine protection areas'' which allow most recreational fishing and some commercial fishing, depending on the method.
