Nelson scored five tries converted one and slotted a penalty to Collegiate's one try by halfback Josh Lennox converted by captain and first five Stephen Perofeta on Monday.
Meanwhile, Wellington scored six tries to one when defeating Christ's 36-8.
Hoskin said lunch at Government House with Governor-General Jerry Mateparae, an afternoon training session and a few hours of downtime was on the agenda yesterday before taking on Christ College today to decide third and fourth place at the quadrangular. Nelson plays Wellington to decide the winner.
"Wellington look real sharp and would have to be favourites," Hoskin said.
