Masterton has taken full advantage of free swimming at Genesis Recreation Centre this week, with almost 1000 people taking a dip on the busiest day.
The pool has been free for swimmers since last week, and will remain that way until Friday.
A $12,000 grant from Lands Trust Masterton will cover the cost of the week.
Customer services co-ordinator Laura McFadzean said it had been a "pretty hectic" few days, and more than 900 people went to the pool last Sunday.
She said everybody has been well behaved, and the warmer weather had encouraged people to come down and "cool off".
