Harris admitted it was not easy to come from behind with the points margins that have been inflicted on them over the past two months.
"It's just having the will to commit to something and having faith it'll work, both on attack and defence - it's not sustained through the game.
"Chasing a scoreboard makes it hard and there were some points that Auckland got because we were chasing a scoreboard."
With a quick turnaround on the schedule as they prepare to host Otago this Wednesday, Northland's injury count is on the brink again.
Jone Macilai suffered a concussion during the Auckland dismantling and his fellow winger Filipo Nakosi is facing time on the bench after picking up a leg injury.
In search of the elusive win, a match against Otago and a depleted North Harbour this weekend could award the Taniwha a consolation prize for their efforts.
However, Harris is intent on drilling the basics into his side to lift their game, both mentally and physically, for 80 minutes.
"It takes a bit of commitment and attitude to build on those things," he said. Auckland 64 (Akira Ioane 2, George Moala 2, Greg Pleasants-Tate, Melani Nanai, Lolagi Visinia, Bryce Heem, Mitch Karpik, Kirk Eklund tries; Simon Hickey 5 con; Jono Hickey con; Calvary Fonoti con) Northland 21 (Warren Dunn 2 tries; Dan Hawkins 2 con). Half-time: 35-0.
