"I've been thinking about it ever since then," he said. "But I can't quite put my finger on what went wrong, something happened and there was a disaster."
The result sees North Force back in relegation contention with all three clubs below them making up ground on Saturday.
Chatham Cup competition next week sees them with a chance for a break but it wasn't on the positive note they were hoping for.
In Northland Premier Grade competition, pre-tournament favourites Kerikeri suffered their second successive loss when defeated by Central Brown 3-1.
Kamo and old rivals FC Whangarei took advantage of their defeat to go top of the table with Kamo defeating Madhatters 4-2 and FC beating Tikipunga 1-0.
Jeremy Rintoul scored a double and Paul Cross a long-range strike before Madhatters struck back with two goals and were pushing hard for an equaliser before Willi Tegerobo grabbed Kamo's fourth.
FC didn't have it all their own way against Tikipunga either, with the visitors peppering their goal unsuccessfully in search of an equaliser.
