He was 15-years-old when All Black legends Kel Tremain, Waka Nathan, Mac Herewini and Ken Gray stayed in his house at the school, as part of the 1963-64 All Blacks tour of Britain, Ireland, France, and Canada.
He said the players slept in the house and even ate with the students.
"We were just so excited they were there. There was about 80 of us in Stanley House and it was fantastic seeing them come in."
The players must have left a lasting impression on Mr Ellis. Emigrating to New Zealand in 1992, he became a fully-fledged supporter. "The day I stepped into the country I had to change colours."
The mayor hopes to watch the All Blacks play Argentina at Napier's McLean Park on September 6, and tries to catch as many test matches as his mayoral duties allow.
