"It wasn't too bad. I think it helps that I did quite a few blind rallies when I first started.
"But it was a tough day for Venita. She was feeling car sick the whole day."
Campbell says his driving has improved since his first rally win 12 months ago.
"I've got another year of experience in a four-wheel-drive car and we have got the car working really well now," he said. "This result gives me confidence going into Coromandel (the next round of the NZ Rally Championship) next month."
There was an important second place for Mt Maunganui's David Holder, teamed with Andy Martin.
Holder rolled his Mitsubishi Lancer at the season opening Whangarei Rally in April. He's battled to find the funding to repair the car and only finished the final touches at 1am on Sunday.
His rally started badly when he nudged a bank only three corners into stage one but he settled quickly and picked up the pace to post a string of second fastest times and climbed to second place.
A battle for third went to young Tauranga driver Mitch James (Mitsubishi Lancer Evo2), who had 2013 winner Ben Thomasen alongside in the co-driver's seat. James was driving in his fifth rally and battled with Tauranga's Wayne Pittams (Subaru Impreza), with a strong final stage time clinching third for James.
There were two notable early casualties among the 50-car field. Third-seeded Rotorua driver Chris Tregilgas rolled his Subaru in the opening stage and Hamilton's Todd Bawden - on a return to gravel rallying after a break of almost nine years - also crashed out.
Bawden was second fastest on stage one and looked to be matching Campbell's pace in stage two but he ran wide and rolled on the final corner.
A team that rose quickly from their 19th seeding were Hamilton's Cottington brothers (Subaru Impreza). Alan Cottington was driving his first rally for eight years - and his first rally in a four-wheel-drive car - and claimed an excellent fifth place.
The closest battle was for two-wheel-drive honours with Ford Escort driver Anthony Jones (Thames Valley) finishing sixth and pipping Rotorua's Ian Wood (Toyota Corolla Turbo) by just 2.6sec.
