Aqua Fitness classes, swim club training and rehab/physio sessions are cancelled until further notice.
The Learners' Pool, spas and slides and the old 25m lap pool are still open and Learn To Swim classes are not affected.
"We acknowledge that this is an inconvenience to our pool users and that it is not an ideal situation for Napier's main swimming pool to be under repair," says Antoinette Campbell, Director of Community Services at Napier City Council.
In the long term, Council is addressing the pool's shortcomings through its Napier Aquatic Strategy, completed in 2015.
A main outcome of the strategy was to build a new aquatic facility for Napier that is modern and fit for purpose.
"This project is currently on hold due to legal action.Following the release of the Court decision, Council will review the next stages of this project."
