Flooding caused the kindergarten to close in December 2017.
More than a year ago Central Kids Kindergarten Rotorua East was devastated by flooding.
Staff at the kindergarten originally thought the building would be out of use for three months but 13 months later they have only just been able to return.
Just before Christmas in 2017, after an overnightdeluge, the staff went to work in the morning to find 20cm of floodwaters in the building.

Inside the Alistair Ave building, a mark on the wall showed how high the water had been.
It was inside the oven and fridge, rubbish bins had moved from one side of the room to the other and sewage had come up from the toilets and spilled on to the floor.
"It was devastating," head teacher Barb Stone said.
"Three-quarters of our equipment had to go in the bin because it was grey water. It was devastating because it looked fine but it was contaminated. The building had to be gutted, stripped down to the bare walls and rebuilt.

"We threw play equipment out, we threw tables out, chairs, anything that was wet had to go in the bin."
Most of the damage was covered by insurance but the kindergarten also applied for grants to cover some things. The rebuild cost about $700,000.
"It was well over budget because we kept finding more stuff that needed to be fixed."

As part of the rebuild, changes have been made to the layout to try and prevent future flooding.
During the closure, the centre's 40 children were relocated to two classrooms in Lynmore Primary School.
Stone said the school had opened its doors to the children and it had a good effect on learning, marketing and helping the children transition to school.
