Northland's track athletes produced a mixed bag of results over their two days of competition.
A highlight for Northland's team manager and regional sports director, Robyn Richards, was the performance of the Senior Boys relay team who placed seventh.
"We were the only team practicing without a baton. The unavailability of one athlete caused a bit of a team reshuffle so that in the end we had two sprinters, a jumper and a thrower."
In other track events, Georgia Brierly (Rodney) made three finals all on the first full day of competition in the Junior 100m, 300m and 800m.
Kelsey Jellick (WGHS) finished fifth in both the Senior 100m and 200m finals.
Kerikeri's Imogen Hull's best performance was a third in her Senior 3000m, whilst Euan Sapwell (WBHS) placed seventh in his Intermediate 100m final and second in his 400m final.
