The wheelchair-accessible seesaw was removed from the George St playspace in April, in the interests of public safety and to prevent further wear and stress on the equipment, the council said at the time.
Yesterday, transport group manager Jeanine Benson said the council was delighted the seesaw had returned but asked it be treated with respect.
"It’s there for everyone to enjoy, but the damage caused in the past has been deliberate," she said.
"We don’t know why anyone would want to smash a seesaw meant to bring a little bit of joy into people’s lives, especially children and those in wheelchairs, but we have a simple request for future seesaw users — just be nice."
The seesaw had been reinstalled earlier this week — "back in action and better than ever".
The repair work was been carried out under warranty and at no cost to the council, she said.
The seesaw was also removed for repairs in September last year after minor vandalism, and returned to service the following month.
