Queenstown's Chamber of Commerce wants a decision to be made over which anniversary holiday the town should mark.
Businesses and schools are divided over whether they should mark the Otago Anniversary on 21 March or the Southland Anniversary, observed on 29 March.
Chamber of Commerce chief executive Ann Lockhart said most Queenstown businesses and schools would observe Southland's anniversary, which falls on the Tuesday following Easter this year.
But early childhood centres closed on 21 March, marking the Otago anniversary.
Ms Lockhart said one way of standardising the anniversary day would be for pre-schools to adopt the same policy as the town's schools.
She said observing just one anniversary day would mean people with children in pre-school and school would not have to take two separate days off work.
Queenstown falls under the jurisdiction of Otago Regional Council.
