A quick glance at his judo CV suggests he is more than capable of ticking that goal off. The Kiwi No 1 in his division last year, Mackenzie, is a multiple North Island champion and at last year's nationals he won silver in his division.
At the recent Wellington Open Mackenzie won gold in the under-18 cadet male open division, silver in the junior men's under-21 division and bronze in the junior men's open division. A member of the Napier and Gisborne clubs, Mackenzie, trains at the Napier club under sensei Andy Truman twice each week and travels to Gisborne for weekend trainings.
The Kiwi team in Tonga will consist of 32 judokas and four coaches, two of whom are from the Gisborne club including King who is the New Zealand men's coach.
"Jason is my idol in New Zealand and technique-wise Shohei Ono of Japan is the judoka I admire the most," Mackenzie said referring to the gold medallist in the 73kg division at the Rio Olympics who is also a two-time world champion.
A Jarrod Cunningham Senior Sports Academy inductee at his school, Mackenzie, has made judo his No1 sport and dreams of Olympic Games selection in the future. However, he is realistic and knows how tough that road is and with the new Olympic cycle under way Mackenzie is also aware of new rules which have been introduced to make judo harder and faster and more television-friendly.
"Commonwealth Games within the next two or three is the first target," he said.
When Mackenzie isn't on the mat he is likely to be found playing football, futsal or working out with his stand-up paddleboard. When he finishes school he hopes to study to become a sports physiotherapist.
■ Napier Judo Club's trainings are on Tuesdays and Thursdays: juniors 6-7pm, seniors (14 yrs and above) 7.15-8.30pm. Sensei Andy Truman said everyone is welcome to give judo a try.
