Dunedin will allow Easter Sunday trading for the first time next year.
The Dunedin City Council voted 10-5 for the policy, with a plan to review it after 90 days appearing to get it over the line.
The policy went for public consultation earlier this year.
While the likes of supermarkets and hardware stores supported the policy, unions were bitterly opposed.
Unite Union organiser Sonja Mitchell asked councillors at a public forum before the meeting to think about the number of workers who would miss out on the Easter break, and the amilies who would also miss out.
