Jellie Park Recreation and Sport Centre’s recreation pool reopened on Saturday.
Said a Christchurch City Council spokeswoman: "The Jellie Park recreation pool was reopened to the public on Saturday, 25 January.
"The closure was for investigation work to be carried out and the relining of the pool is scheduled for later this year.
A city council memo last week said the pool tank was to be relined due to a significant number of tiles failing and customers and staff receiving cuts to their feet.
