Greerton, especially, caused a major upset when they defeated last year's champions Mount Maunganui on the same ground last weekend.
Posting a modest 194/5, with Ben Williams top scoring with 81, Greerton would have been forgiven if they had thought they were out of contention to make the final.
However, some great fielding from the visitors, including three run outs, meant the home side were all out for 184.
Cadets had a more comfortable journey to the final when they took on Tauranga Boys' College at the Tauranga Domain last weekend.
The piled on 214/9 with Jono Boult and Matthew Drake grabbing half centuries. Boult backed up his batting form taking four wickets to help remove Boys' College for just 145.
Going on form Cadets would have to be the favourites leading into the final. However, if last weekend is anything to go by, Greerton will have plenty of confidence and will be looking to repeat the form they showed against the Mount.
