The Dunedin policeman has coached premier rugby for eight years and his teams have now made the final five times.
Baker was head coach when Dunedin beat Southern 11-10 in 2009. Mark Scully and Ross Hanson were his assistants.
Baker's Dunedin teams finished runners-up to Southern (13-9) in 2007, to Alhambra-Union (26-10) in 2008 and to Taieri (24-22) last year.
''Of course we can win,'' Baker told the Otago Daily Times.
''We've lost games by low single digits. We just have to put it on the park this week.''
The Dunedin team has taken a lot of confidence from the way it came back and held out a rejuvenated University A in the semifinal last weekend.
Dunedin nudged in front by three points when fullback Liam Edwards kicked a penalty goal.
The last five minutes of the game belonged to hooker and captain Sam Anderson-Heather, No 8 Gareth Evans and openside flanker Hugh Blake, the old hands in the Dunedin team, who inspired the pack to hang on to the ball with the pick and go.
It was this go-forward ball by Dunedin that deprived the students of possession and shut them out of the game.
''They are class players and stamped their authority on the game,'' Baker said. Dunedin has the stronger tight forwards and will be keen to exert pressure from the scrums and the lineouts.
Lock Richard Thompson took lineouts off University throws and the front row kings of Anderson-Heather, Will Henry and Sean Smith will dominate the scrums.
The breakdown could decide the game because both sides have classy loose forwards.
Evans, Blake and Martin Swaffield are a dynamic trio for Dunedin but they can be matched by Taieri's Charlie O'Connell, Willis Scott and Brodie Hume.
Taieri has the skills and aggression in the backline to rip other teams apart. They have a skilled director of operations in Hayden Parker at first five-eighth with his skilful passing and tactical kicking.
The midfield combination of Ben Nowell and Kieran Moffat is lethal and will run in tries if given a chance. The two Dunedin backs who are expected to have an edge are Brad Weber at halfback and Liam Edwards at fullback.
They both have blistering speed and know how to score tries. Edwards demonstrated this when he scored two tries in the semifinal against University A. Taieri coach Jason Macdonald has recognised Edwards and Weber as the ''danger men.''
''Edwards is dangerous on the counterattack and has a good kicking game and Weber has acceleration, a good pass and brings variety to his kicking game.''
Taieri has superior fitness to most other teams and plays the game at pace for the full 80 minutes.
''We just have to hold on to the ball and starve them of possession,'' Macdonald said.
''We have to make them keep tackling us and they will get tired getting up off the ground.''
Both teams will be hardened for the battle at Forsyth Barr Stadium tomorrow after winning tough semifinals last Saturday.
Macdonald is used to finals rugby. He captained Dunedin when it won the banner in 2005 and coached Taieri to its banner win last year
