McCall hit his bag to lose the second hole giving Balneaves the early lead but McCall drove the third green making a birdie 3 to even the score.
Balneaves took back the lead when McCall three putted the fourth green and went two in front with a birdie 3 at the fifth.
Then came the turning point in the match with McCall winning the sixth, holing a 6m putt on the seventh for a half and squaring the match by birdieing the eighth.
McCall hit the front when Balneaves three putted on the ninth and a par was good enough at the tenth to put McCall two up.
The pair halved the next five holes before McCall made an impressive birdie 3 on the 16th to claim victory.
Brent McEwan (St Clair) won the senior plate beating Tony Giles by 4 and 2 while Matt Tautari (Queens Park) retained his unbeaten matchplay record this year downing Chisholm Park schoolboy Cody McMullan in 14 holes. Ryan Bellamy from Port Chalmers took the intermediate title on the final green, Geoff Shaw (Maniototo) won the junior championship while Murray Edgar was the best of the over-50 golfers winning the masters event.
Play during the afternoon was delayed for almost an hour when the greens became unplayable after a deluge of rain and hail.
A resumption of play was only possible after greens superintendent Craig Parata called in his team to squeegee the water and hailstones off the putting surfaces.
After two nail-biting quarterfinals on Sunday afternoon, the semifinals were one-sided affairs with top qualifier Balneaves and New Zealand No 1 McCall getting into the all-Southland final with holes to spare.
Balneaves halved the first four holes with Otago's Michael Smith but took the lead with birdies on the fifth and eighth holes. He turned three up before Smith bogeyed the Glen hole putting Balneaves four up, a lead which he increased to five with a birdie 4 on the par five Tipperary hole.
Smith won the 14th with a par but the match finished on the following green.
McCall was one under par and one up at the turn over Scott Hellier but he put the result beyond doubt winning four of the first five holes on the homeward nine.
