In this year's inaugural Super City competition, St Kentigern finished third behind perennial front-runners WBHS and Kings and ahead of AGS.
Involved in hockey at club, school and representative level - like many starting at the Hatch Cup tournament - Jimmieson says his game has benefited from the coaching he has received.
"Along with Ramesh Patel, who oversees the whole hockey programme at school and is the assistant coach of the 1st XI, I have also been fortunate to have been coached by Andy Hayward and Helmut Lala and others," said Jimmieson, who also played for the Howick Pakuranga premiers this season along with the Auckland under-18 (for whom he was the leading goalscorer) and under-21 teams. The under-21s won the national title.
The coaching from Hayward is especially beneficial.
It gives Jimmieson the opportunity to learn from one of the best drag flick exponents in the game here, something Jimmieson, 18, is keen to develop.
"I finished with a .4 success rate this season which is not too bad."
Already selected with St Kentigern teammates Richmond Lum and Daniel Guthrie in the NZ Under-18 Tiger Turf squad, Jimmieson is looking forward to representing New Zealand at that level in Australia next year.
While he played in the midfield for St Kentigern, he has also played fullback and will continue his development next winter when he switches to play his club hockey at Somerville where he will be coached by Charlie Oscroft.
Given the success of the sport at St Kentigern - they were the third-best Auckland school at this year's Rankin Cup, again finishing ahead of AGS - the improvement in a sport which, at this stage, plays second fiddle to rugby and soccer, is putting the pressure on proud principal Steve Cole to come up with the funding to add a water-based turf to the sand surface used by the younger grades at the school.
"That would be great," said Jimmieson. "At present all our training is done at Lloyd Elsmore Park." It would really help to have blue turf.
