A hat-trick from Anna Liddington - taking her side's golden goal award with 10 for the season, over the other main contender Nikki Osborne - did the damage against Hora Hora. However goals to Taylor Jenkinson, Trudy Derbyshire, Lilly Molloy Wolt and Osborne made sure of the win.
Kate Liddington noted there was quite a bit of rain and upon turning up saw the pitch they were playing on was in a horrendous condition.
"Couldn't believe we were playing there," she said. "We brought home the silverware! Hopefully there's a nice big spot in the trophy cabinet."
In the main event for the women's Stafford Choat, Kerikeri High School's firxt XI went down narrowly to Kamo, also playing at Morningside Park.
Kerikeri Siteworx's win is the Waipapa-based club's second title for the season, after the Harcourts Masters team took out the Northland Men's Division (NM2) league title earlier in the season.
The Kerikeri men's premier team also still hold a chance, albeit a slim one, of winning their league.
Kerikeri Siteworx women: Lili Molloy Wolt, Niki Osbourne, Trudy Derbyshire, Jenny Lee, Aiden McManus, Natalie Pickery, Anna Liddington, Louise Cartwright, Taylah Jenkinson, Ellie Liddington, Natalie Sydall (captain), Maki Dalton, Iris Kaiser. Coach: Paul Culbitt; Manager: Kate Liddington.
