The state government has committed to an immediate review of the Port Stephens-Great Lakes park if re-elected.
Primary Industries Minister Niall Blair said the commitment followed a vocal community campaign on the issue.
Liberal candidate for Port Stephens Jaimie Abbott said the review would give residents the chance to have their say about zoning and management with a proper community consultation process.
“Our beautiful waterways are a vital part of our local lifestyle, used by the entire community, and this is a huge win for everyone - from recreational and commercial fishers, to boaters, tourism operators and families who spend time in our beautiful waters," Ms Abbott said.
The Newcastle Herald reported in February that both major parties had agreed to a review of the marine park.
Port Stephens MP Kate Washington promised a Labor government would initiate a marine park review within 12 months of forming government.
Mr Blair accused the Labor Government of establishing the marine park without proper consultation or a scientific threat and risk assessment.
“Minister Blair’s assurance is the result of a great team effort, from local fishers, stakeholders and the community working together," Ms Abbott said.
"Particular thanks are directed to David Donovan, whose 2000-signature petition was used alongside mine."
Many believe a review of the sanctuary zones, that make up 17.3 per cent of the park, is long overdue.
