"I've got about fifty or sixty All Blacks jerseys that I've collected for over thirty years," he said.
"I was keen on this one because I don't have a 2017 one and I try to get one from each year.
"I have most styles covered … I've probably got the most white jerseys, the All Blacks only wore white jerseys on about eight occasions I think and I've got about five of them."
His collection dates back to 1924, he said.
"I actually think this one will go for about four and a half, five thousand I reckon.
"I think it'll go pretty high, it's obviously for a good cause so the more they can get the better."
