"We understand the importance of this area to the community, and know that scallops have been traditionally important to recreational fishers."
Anderson said the decision to close the harbour was made after extensive consultation with stakeholders, public and tangata whenua as part of Fisheries New Zealand's twice-yearly review of catch limits.
"When our fish stocks are declining, we decrease catch limits, and in some cases if it's necessary we will close the fishery, like the Kaipara Harbour. As the fish stocks recover we can increase the amount people catch.
"While the closure is currently open ended, we will continue to review the closure as results from further research becomes available.
"A broader focus to address issues related to the habitat in the Kaipara Harbour will also be required to restore the fishery," Anderson said.
