Fullback Luke Myers scored three of Collegiate's first four tries, completing his personal quartet in the second half. Impactful No 8 Josefa Namosimalua backed up superbly to also get four tries - the last two coming off brilliant offloads in the tackle which he collected basketball-style.
Outgunned, WHS at least played the full 70 minutes this year and avoided the 2019 scoreline of 96-0, with flanker Andre Awatea and reserve Tawana McGrath producing a couple of try-saving tackles.
In the under-15 game, Collegiate edged home 22-20, with second-five Monty Sherriff scoring all four tries and adding one conversion.
