Clements ran in a time of 37.28 and Hutchinson in 41.23, three minutes faster than her time when she won the 2016 event.
With only one more event to go in the 2017 Sport Northland Run/Walk Series, the NorthCloud Leaderboard has already been won by Linford and Maria Akkeson.
Despite this the ASB Kerikeri Half Marathon will still have a lot on the line for runners as both Young and Mills sit on 21 points each in second place.
The ASB Kerikeri Half Marathon is set down for November 18 which will be held in conjunction with the New Zealand Half Marathon Championships.
The New Zealand Half Marathon Championships attract some of New Zealand's best runners and with the Kerikeri Half a largely flat course, personal bests are likely.
The New Zealand Championships will also include a large number of Masters runners aged from 35 years through to 80 years-plus, with each competing for New Zealand titles in their respective age brackets.
