Mr Sharp said his invitation to the boys and their parents to join him for a day with the Bay of Islands Yacht Club was genuine.
"We'd treat them like kings ... No matter how they got their hands on it, they brought it back. I'd love to take them out on the water. It will also give them a new perspective on what disabled people can do."
Mr Sharp said he couldn't put a value on the chair, which was his ticket to freedom after he lost the use of his legs in a motorcycle crash eight years ago.
Last year the 59-year-old started the Northland branch of Sailability, an organisation that teaches disabled people sailing. As a result of publicity around the wheelchair incident he had been contacted by a Paihia man who had lost the use of his legs through a rare illness but had now joined his sailing programme.
Another positive spin-off was experiencing the power of social media when people felt an injustice had been done.
"It highlights how the community feels about looking after its own members. It's magic. You're not alone," he said.
Mr Sharp went straight back to coaching on Thursday and left his wheelchair in exactly the same spot on Waitangi jetty.
"I'm not going to change. The community has been very cool about looking after my stuff. The people who took it simply didn't understand."
Acting Sergeant Mark Roberts, of Mid North police, said the return of the wheelchair - like returning property stolen from German backpackers two weeks earlier - was the best part of his job.
