Greg Smith will be crucial, coming off his clutch 101 not out against Marist. This season he has scored 324 runs at an average of 81 and strike rate of 91.
He will need a partner as representative batsman Daniel Burgess has returned to university and Max Carroll is unavailable.
It is likely that veteran Tom Lance will come back into the XI, although it will be more for his spin bowling than top order batting.
Runs will be needed from amongst Zeb Small, Carter Hobbs, Matthew Boswell, Chris Sharrock, Brendon Walker, Simon Badger and Robbie Power.
Kāpiti have not run up a host of big scores this season but they have a bowling attack which proves a handful, having dismissed the otherwise undefeated Red Star twice.
The game starts at midday, weather dependent.
The Premier 2 and 3 finals are also on Saturday. The Premier 2 game starts at 12.30pm with Premier 3 at 1pm.
