ST Hitec was first established in 1999 operating out of a small workshop in Newmarket. The initials ST referenced the owner, Soichi Tate who, prior to moving to NZ,  worked as head mechanic at Nissan in Japan. The main focus at ST Hitec was performance - the first step was providing and fitting the performance parts - the second step, testing and tuning the car on a Dyno machine, which was Soichi's speciality.  With the experience he bought with him from Nissan, in particular his knowledge of the RB and SR engines, it wasn’t long before the name ST Hitec became synonymous with performance car tuning in New Zealand.  If you attend a car show, you will soon notice the many cars sporting the ST Hitec sticker – many well known performance cars in New Zealand can attribute their success to Soichi's tuning, one in particular, the BNR32, VeilSide equipped 800HP R32 Nissan GT-R which has won many awards in many different competitions.  ST Hitec also pioneered many import vehicle events in New Zealand, such as the VeilSide R34 GT-R Land Speed Record, Top Secret Drag Day and more recently the D1GP NZ Series.  At the end of 2015, after 16 years tuning performance cars, Soichi made the decision to sell ST Hitec Ltd.

New owners Graeme and Iain Clegg brought in Stewart Mearns as General Manager, Stewart takes care of the day to day running of the workshop and is the primary in house tuner. Stewart was the perfect choice to take ST Hitec forward, a qualified automotive engineer with over 30 years experience in the automotive industry in New Zealand, he brings a wealth of mechanical knowledge and experience with ECU's and electronic vehicle management to the team. Stu's background includes;stewart-mearns
- 4 yrs at GM Holden
- 3 yrs spent in a performance shop building/ modifying V8's & 6 cylinder engines into all manner of vehicles.
- 3 yrs at Nissan New Zealand, competing in 93 Nistec competitions throughout Australasia gaining 3rd place in World finals in Yokohama for engine system diagnosis.
- 3 yrs at Honda New Zealand as Workshop Manager again competing in Honda International Technical Competition in Thailand & Japan.
- 14 yrs back at Nissan New Zealand as a Technical Service Representative then moving to Aftersales Operations Manager - responsible for Nissan Dealer Network Service & Parts Operations.  Stewart has also been involved with racing for many years - 2.0L touring cars, NZV8 & GT3 Porsche series cars, as well as a few GT-R's – an engineer a heart, Stu has built own engines, drivelines, and has fabricated many bespoke components to aid the reliability of the RB26.

ST Hitec also sponsor an R35 GTR that is driven by owner Iain Clegg.
In his first year competing in the NZ Superlaps Series, he entered the R35 in the Pro Street class and finished 2nd overall.  The final round at Hampton Downs however, was his – setting a lap record of 1.10.  With a slick tyre we ran a personal best lap time of 1.08.

Iain officially became the driver of NZ's fastest R35 GTR at Meremere Dragway, with a 1/4 mile time of 10 secs flat at 147mph on it's first run - at this time the R35 was running 1000hp. Becoming NZ's fastest R35 GTR with it's previous set-up, this car has evolved yet again. To go with its 4.1 fully forged and stroked engine, the R35 now has a GTX3582R Twin Turbo setup, as well as custom inter coolers, a custom plenum, 6 x 1000cc and 6 x 1500cc injectors, 3000hp fuel pump, GT straight cut gearset, heavy duty clutch and front clutch, heavy duty driveshaft and the brains behind it, a Motec M150 ECU - fill her up with E85 fuel and you've got a full street legal monster that pumps out a whopping 1450hp.

ST Hitec's R35 GTR has set NZ Superlaps Pro Street track records at Manfeild racetrack, Bruce McLaren Motorsport track, Hampton Downs International Circuit and Hampton Downs National Circuit - the results after 6 rounds say it all - Iain annihilated the competition with a sensational 1:07.067 at the final round at Hampton Downs and took out the series win in the Pro Street Class for 2017.  Remember this is a full street trim car, Registered and Warranted, weighing 1871kg's without driver.

The workshop in Mt Wellington has undergone many changes too - the dyno room has been extended and the air extraction system upgraded to remove the harmful exhaust output safely out of the building - the addition of an insulated internal wall and an insulated door means a huge reduction in noise when a car is on the Dyno. To cater to the growing demand for modified engines, a dedicated engine build room has been installed within the workshop, providing a dust free, air conditioned environment for all engine work to take place. And for our customers they can now relax in our comfortable waiting area, enjoy a good cup of coffee and read a magazine.

Racing cars aside, the team at ST Hitec are committed to providing our customers with excellent service and workmanship of the highest standard. We are the number one tuning and performance workshop in New Zealand and are determined to stamp our mark on the global industry.
