But Kaikorai set up their victory with two quick tries in the third quarter of the game.
They took a 22-17 lead into the halftime break.
Harbour had the ascendancy up front and dominated the scrums.
Kaikorai went wide at every opportunity, but it found more gaps through the middle ironically.
They crashed over for three tries.Openside Slade McDowall had a dominant half and Ben Miller's tactical kicking helped put his side in good positions.
Harbour, for their part, blew too many attacking lineouts. The Hawks did not execute well in that phase.
But they struck early in the second to level the score. Centre Aleki Morris-Lome scored in the corner after the Hawks had been battering away at the line.
But Kaikorai replied immediately. Miller ghosted through a gap and, after several passes, fullback Charlie Breen dotted down.
Then Otago lock Will Tucker broke the line and flicked the ball to McDowall and angled his way to the corner.
