The facility will be closed from November 19 for about five weeks after some ceiling tiles were found to be loose.
After the tile issue was noticed last month, management closed the pool's two hydroslides, ''lazy river'' feature and a small area of the leisure pool as a precaution.
Queenstown Lakes District Council sport and recreation manager Simon Battrick said the pool closure was unscheduled but essential.
“Movement of ceiling tiles in a 10-year-old aquatic facility is not uncommon, especially given the humidity inside and the outdoor temperature's fluctuations in our alpine environment.
“Removing all the tiles at the same time is our preferred solution as it means the work can be completed most efficiently. This involves draining all pools and erecting scaffolding, hence we need to close the pool hall to minimise risk to our customers and staff,” Mr Battrick said.
Staff would be allocated other roles and were contacting all affected clubs and regular user groups to discuss the closure and potential alternatives.
QLDC Sport and Recreation is also working to open Arrowtown Memorial Pool earlier than its scheduled date of December 9.
All other facilities at Queenstown Events Centre, including Alpine Health and Fitness gym and group fitness studios, sports fields and the indoor stadium, are unaffected and will operate as normal.
All facilities at Alpine Aqualand will close as normal at 8pm on November 18 and then remain closed while the initial phase of the work is completed. The pools are scheduled to reopen on Boxing Day.
