That is despite the District Licensing Committee (DLC) overriding the policy by granting a new licence last year.
The Sale and Supply of Alcohol Act 2012 gives local councils the ability to put a local alcohol policy in place in their district and the Whanganui LAP stipulates a cap of 14 off-licence premises for the district however the DLC granted the 15th licence last year.
Swarbrick commended the council's efforts in introducing the LAP and the aim to minimise legal challenges from suppliers.
"You did get a lot further than Wellington, Hamilton, and Christchurch councils," she said.
Swarbrick said there was no current legislation to prevent the DLC from overriding the LAP regulations and her bill would address that loophole if it was passed.
The DLC's decision led to the Safer Whanganui coalition describing the LAP as "toothless" and the council supported its members in signing a letter to Justice Minister Kris Faafoi asking for local alcohol policies to be given more teeth, so they could be enforced like any other bylaw.
Faafoi had confirmed that a review of the act was scheduled within the current term of Parliament, however, Swarbrick said there had been no indication of the scope or the timing of the review.
Auckland councillors have voted in favour of supporting Swarbrick's bill and Whanganui councillors were to discuss the matter at Tuesday's meeting. However, as mayor Hamish McDouall and a number of councillors were attending the funeral of Whanganui artist and former district councillor Ross Mitchell-Anyon on Tuesday afternoon, the meeting was adjourned until 1pm on Wednesday, May 11.
