Many of the older youngsters scrambled to get his autograph on scraps of paper.
Meanwhile, the children's smiles said it all.
Rolleston, who appeared overwhelmed by all the fuss, told the Bay of Plenty Times he was excited to be asked and jumped at the opportunity when he heard about Homes of Hope.
"I was really pleased to be asked and keen to be involved. I think it's brilliant for the kids, who would rarely get an opportunity to do something like this," he said.
Rolleston said he could relate to some of the struggles the children went through.
He was 100 per cent behind the Homes of Hope and its charitable works.
Homes of Hope chief executive Hilary Price said Rolleston was a "humble, fantastic young man" and she felt blessed to have him and Mr Alvarez and his team on board.
