First half goals to Hikurangi's Karen Brown and Sarah Morris were enough for them to secure the reserve A women's hockey title over Old Girls.
Hikurangi went into the game as favourites, after finishing the round robin in top spot, with their coach Tony Organ believing his team could win.
"These guys deserve it ... they always believed in it from the get-go so it was just a matter of getting it done," Organ said after Saturday's match.
Hikurangi applied early pressure to the Old Girls defence and it didn't take long for them to turn it into points, with Brown converting a penalty corner to go one ahead within the first 10 minutes.
Old Girls were then chasing their rivals and fought hard to attack, but the Hikurangi defence held strong and composed.
