Steinmetz, the former All Black who now lives in Wellington, turned out for both the Highlanders and Hurricanes in his playing career.
The midfielder played 11 games for the Hurricanes in 2000-01 before transferring to the Highlanders, where he played 22 games.
He moved to Ireland and ended his playing career there.
''I've got a foot in both camps on Saturday night. I'm in a no-lose situation,'' Steinmetz joked.
''It should be an entertaining game. You look at both sides and they have some great players all over the park. The wings for both sides are important players.
''You'd have to say if Julian Savea and [Nehe] Milner-Skudder do not score a try then the Highlanders will win. But that is the flip side with the Highlanders. If their wingers don't score a try then the Hurricanes might win.''
Steinmetz (38) had been to see the Hurricanes play a few times this year in Wellington and said they had grown through the year.
''You could say they got off to a bit of a cushy start. Things seemed to go for them and they got wins, with a bit of luck. That helped them, built their confidence and belief and they kept on winning.''
Steinmetz, who works for Fuji Xerox in Wellington, said he played with Conrad Smith and Ma'a Nonu a bit at the end of his career. Apart from those two, all the Hurricanes were new to him.
The former second five-eighth said he had fond memories of his time in Dunedin with the Highlanders.
''I started off my time with the Hurricanes but I didn't get much playing time in behind the likes of Tana [Umaga]. Then I took off down to the Highlanders and I really remember the times down there.
''They were a pretty exceptional group of guys and players, The one difference I found between the two franchises is the players were a lot closer down in Dunedin.
''They had a really strong leadership group, guys like Anton [Oliver], Taine [Randell] and Tony [Brown].''
Steinmetz does not have any formal role in rugby now, although he advises the Hurricanes on post-career player development and coaches a bit of schoolboy rugby.
He is married to former Black Sticks hockey player Rachel (nee Sutherland), and the couple have three children, Micha (7), Luca (5) and Quin (3).
The whole family will be at the stadium on Saturday night for the final.
