ST Hi-Tec 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 technician at Nissan in Japan. The main focus at ST Hi-Tec was performance – The first step was providing and fitting performance parts – The second, testing and tuning the car on a Dynamometer, which was Soichi’s speciality. With the experience he brought with him from Nissan, in particular; was knowledge of the RB and SR engines. It wasn’t long before the name ST Hi-Tec became synonymous with performance car tuning in New Zealand.

If you attend a car show, you will quickly notice many cars sporting the ST Hi-Tec sticker – Many well known performance cars in New Zealand can attribute their success to Soichi’s tuning. The BNR32, VeilSide equipped 800HP R32 Nissan GT-R in particular, has won many awards in many different competitions. ST Hi-Tec 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 Hi-Tec Ltd.

ST Hitec’s R35 GTR has set Time Attack NZ Superlap Pro Street track records at Manfield 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.

We entered our R35 in the Thames Valley Car Club half mile challenge on Hamilton Rd, Ngatea. Our first run was at 315km/h, smashing the old record of 285km/h. Remember this is a full street trim car, Registered and Warranted, weighing 1845kg’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 removed to keep vehicle’s cool during tuning – the addition of an insulated internal wall and an insulated door means a huge reduction in noise when a car is on the Dyno.

Catering 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.



Our professionals will perform diagnostic tests, fluid flush and fills, engine replacement, oil changes, and total vehicle overhauls.
