Hamilton's Gallagher Aquatic Centre swimming facility will close for six weeks, from March 16, for a range of maintenance and renewal work.
The complex, adjacent to Melville High School, is the smaller of the two facilities in the Hamilton Pools operation, overseen by Hamilton City Council.
Council's aquatic facilities manager Stuart Davidson, said in a statement the six-week closure stems from a management desire to combine a range of planned work.
"As part of asset management, we plan ahead for work our facilities need," Mr Davidson said.
"Pools are popular facilities, and the machinery in our plant rooms has moving parts. We need to manage and replace those from time to time to ensure we can meet the needs of our customers.
