A period of pressure around the ruck and maul paid off for Kaitaia with a try to Josh Mane, converted by Jurlina.
The score was 14-13 in Kaitaia's favour with 15 minutes to go and the game seemed likely to go to the wire.
After recovering from a kick-off error, Kamo worked their way deep into opposition territory and were rewarded with another try, to Jacob Matiu, which was converted by Currie.
Kamo managed to withstand a late Kaitaia charge and win the secondary schools' competition.
Matiu, Carew Hapi and Hewitt were the standout players for Kamo while Josh Mani and Jurlina had a strong game for Kaitaia.
