It was the squad's mental attitude which was letting them down, the coach said.
"The skills and talent to win are all there, it's just a matter of belief and the team finding that push and desire to go the extra mile."
Nock is adamant his squad will turn their luck around, if they start believing in themselves and in their cause to do well at nationals - a point which was stressed at an "honesty session" the team had following games on Saturday. Northland are still dealing with a few injury concerns - Beau Dickens (hamstring), Jimmy Horsford (back/ankle) and Rhys Te Nana, who is managing a serious knee injury, were ruled out of playing at the weekend, and Nock is hopeful at least Dickens and Horsford are fit for the Mount Maunganui Sevens on January 2.
The squad have three training sessions before Christmas and will train after, until they leave for the Bay of Plenty on New Year's Day.
A team will then be finalised for the Pub Charity New Zealand National Rugby Sevens Tournament in Queenstown, from January 7-8.
