"If anything comes out of this, it shows we might have the odd scumbag in our community, but we also have some super, super special people too," Mr Henwood said.
"The support has been awesome, it's just been so nice."
Mr Henwood said he had made raising funds for people with cystic fibrosis his "pet project", after two young people close to him were affected by it.
"It's not one of the big charities around," he said.
Mr Henwood had not heard from the "low-lifes" who stole the donations.
"No word at all. They haven't popped in to say sorry.
"What they took off people with cystic fibrosis, they have to live with," he said.
Cystic Fibrosis Association Bay of Plenty branch chairwoman Nicole Wakerley was delighted people had stepped forward to help.
"It's just amazing, donation boxes are actually really helpful," Mrs Wakerley said.
