Kai Iwi School is known for its murals and there is a mosaic one that Mrs Foote instigated when she was still fairly new to the school and two murals painted by pupils with guidance from artists Cally McKenzie and James Graves.
The school swimming pool has a taniwha mural painted by pupils last year and now the changing shed wall will be decorated by the latest mural made with more than 4000 bottle tops.
"It has been a child-led project," said Mrs Kidd.
"Rather than draw the design on the board, we encouraged the children create the design with the bottle tops."
The result is a stunning underwater scene with an array of sea creatures swimming across it and there is even a human skull resting on the sea floor.
Traedyn Christiansen 10, said he used a lot of blue bottle tops for his section.
"My job was filling up the water," he said.
Eden Winton 8, said she made a star fish and helped with the water.
Ryan Morrison 9, said he created the black and white orca.
"I realised it was going to be too small compared to the octopus so I just made it with just its face peeping in at the side."
Maddison Frankhouser, 8, said she worked on filling in the blue water around the sea creatures and it was fun.
The bottle tops have been glued to the board with Gorilla glue but Mrs Foote said the plan is to find a few kind tradespeople who can supply some screws and labour to affix the bottle tops more securely.
"We don't know how well the glue will hold once it is out in the weather," she said.
The Kai Iwi School is usually open to the community during summer but the teachers said it needs a sealant spray treatment so will not be open until term 1 next year.
