The four teams ended the round-robin competition within five points of each other.
Upper Clutha has recorded 11 wins to the 10 of the other three qualifiers.
Upper Clutha has had the wood on Arrowtown all season, winning 25-3 in round two, then 48-12 in the ninth round in Wanaka.
Upper Clutha has been a much improved and more consistent side this season under head coach Paul Glynn and manager Robert Nolan.
Strong numbers and a good team culture among a largely youthful team have all contributed to two seasons of improved showings from the Wanaka-based side.
Arrowtown knows what it has to do. It was a finalist last season and will be keen for a repeat.
It has been running into good form, having had five wins on the bounce leading into the semifinal, including wins against Cromwell and Wakatipu.
It locked up the prestigious White Horse Cup for the season last week with victory against Matakanui Combined and is clearly not just there to make up the numbers.
Wakatipu, which won the title last year, takes on Cromwell on the back of some disappointing recent form, having lost its past two games against Arrowtown and Maniototo, and it has struggled against Cromwell in both games during the season.
The first game between the two at Cromwell resulted in a 31-31 draw which went to the judiciary following a dispute over the score.
In the return fixture, Cromwell recorded a 22-19 win in Queenstown.
Wakatipu will need to be at its very best against a Cromwell side which has won its past three games, including a very good 39-34 win over Upper Clutha two weeks ago.
The Queenstown-based side has scored an astonishing 42 points per game this season and looks dangerous out wide with the likes of Kapa Moeke and Mark Te Whaiti in good form.
Cromwell has been guilty at times during the season of not concentrating for the full 80 minutes and will need to have this side of its game nailed if it is to make the 2018 final.
