Whangarei's Carolyn Younger, who recently won gold in the half marathon and silver in the standard individual triathlon (W45-49) in Auckland at the World Masters Games and last year's Paihia winner, could only manage second place as Kerikeri's Maria Akesson won in 33.28.
Third home was Whangarei's Katie McVerry in 36.37.
The NorthCloud Leaderboard for the 2017 Sport Northland Run/Walk Series will see Linford and Akesson remain at the top with Mills and Younger also retaining their second places after the third event in the series.
Paihia turned on great weather for the 1070 competitors who ran or walked over one of two distances.
This year's event included the opportunity to enter in a pram run section. For Rhys Colmer pushing a pram was no barrier to running and completed the 8.7km course in 34:50 Finishing in tenth place overall.
