Judging Team


Sam Mercer

Sam has been leading the judging team since 2013. He has held different management positions in the automotive industry for over 10 years and is currently contracted to Holden NZ as a Sales Development Manager. His love of cars has seen him owning a workshop and importing cars for a number of years. Back in 2006 Sam built himself a 9 Second Evo 3 drag car that he campaigned in a full interior road legal state. He appreciates all sorts of vehicles from his time with a V8 parts wholesaler and it shows in his current vehicles a Ford Escort Cosworth, GTR Skyline, 2009 STi and just for a bit of fun he has a 1000cc Streetbike powered Golf Cart.



Marcus Rose

Marcus' passion for all things noisy and fast began on his farm on motocross bikes. As a kid, he rode the paddocks and street on motorbikes before progressing onto the four wheeled variety. His rides have consisted of Mazda 626, rx4 sedan and a super quick Gtti Charade! Things got a bit more full on after that, completing a full rebuild on a Nissan Navara mini truck, dubbed H8BMPZ. This competed in the show scene, and truly ignited the mini truck following. From there, Marcus’s job with Fusion took him to the States, travelling the insane automotive show scene over there as well as a long stint of 10 years with Red Bull. Since then, Marcus and his fiancé Bex have gone back to their roots buying a nifty wee Mazda 1300 and currently go on family cruises in their series 2 RX2 running a 12a PP.

Nathan Sandford

Nathan has been in the automotive industry his whole life as a mechanic, workshop manager and did a season with Toyota Racing Series as an engine builder. Currently he’s working for Mitsubishi as a Service Advisor. You may recognize him as owner of Boosted Performance which featured on the TV show Import X building the 1UZ AE86 and Twin Turbo VQ45 Navara. He is also made a guest appearance on Meke my Waka which aired on Maori TV. Nathan enjoys anything on 2 wheels including his dirt bike and will be representing NZ in BMX at the World Champs at Vector Arena in July. He has a passion for Ford vehicles such as Laser Tx3 Turbo’s and lately he has upgraded to a 1981 GL Mk5 Cortina.


Jess Darlington

Jess brings some experience to the judging team, shown in his first engine swap to a $700 RX2 back in 1989 in his crazy mother’s carport. From there, Jess developed a love for Toyota’s first turboing a 4AGE back in the early 90’s and a string of 1UZ conversions in later times. Jess has laid his hand to many past award winning cars and even has a few trophies of his own, including Best Toyota and Best Ute. Jess is never afraid to try something different and question the norm when it comes to modified vehicles. Currently he does rally sprints and hill climbs in his corolla and chops up motorbikes for a bit of fun.


Clint Field

A mechanic by trade, Clint’s interest in cars began at a young age where he worked part-time at the local gas station and raced go-karts. Clint began his working life at a workshop specializing in Hot Rods and modified cars where he was employed for 10 years. He then began working as a low volume vehicle certifier, which he has been doing now for 7 years. Over the years Clint has owned a number of modified vehicles, including early Ford Escorts, a turbo R32 Skyline, a bagged 1UZ powered Nissan Navara and a string of V8 powered Valiants culminating in his current project, a turbo V8 powered VG Valiant which gets regular use both on the track and on the street.


Scott Finn

Scott is the longest serving team member with 10+ years experience with the 4&Rotary judging team. He has been working with some car clubs for close to 20 years now, carrying out fabrication for members of GGON, ONBOOST and MR2OC. He has owned and modified a few performance cars himself, a Nissan GTiR, Mitsubishi Evo and until recently an impressive Toyota MR2. Scott has a passion for anything fast and certainly has an eye for detail and function. By trade he is a fabricator and refrigeration engineer which allows him to be involved in a range of projects.


Andy Cheals

Andy's interest in cars started at an early age with his Father’s passion being passed on. Having a few ‘clunkers’ (Mainly Cortinas and Escorts) in my younger years I eventually moved on to the RWD Starlets of which I have owned my current one for 13 years, now being powered by a JC 13B Bridgeport turbo. I have been involved in the Automotive industry for nearly 25 years since leaving school, starting out as a spray painter before doing a few years of auto electrical work and then moving into parts supply. I have been involved with 4 and Rotary for 10 years, starting when I first showed my car at the ‘06’ Nationals. Also I have been fortunate over the years to help build cars with mates and crew for the FC Datalogit drag car which won a few show awards as well as claiming the fastest 13B NZ title when it was racing.


Jacky Tse

Jacky is the owner of Auckland workshop Jtune Automotive. Jtune specialize in modifying NZ’s best JDM style street cars, circuit cars and show cars. Jacky has been in the car scene for more than 10 years, he’s done his time judging in Autosalon car shows as well as the 4&Rotary series. He’s owned and built many cover cars for local publications as well as overseas “Superstreet and Speed Hunter“. Not only do his vehicles feature in them but he also writes part time for a number of different magazines and newspapers. Jacky is always keeping up to date with what’s new in the industry from latest trends to new products and innovation.



Troy Smith

I have been involved in 4 n Rotary over the last decade, I was first introduced to it back in 2001 where I travelled up and down NZ showing of my Mazda's over the years, I won several awards consisting of Best RX, Best RX overall, Best RX engine bay and Peoples Choice over a collection of 4 to 5 different cars I have had in my possession. Over that time 4 of them were featured in NZ Performace Magazine, two made front cover, also made it to the big screen and 4 & Rotary videos. I have attended Auto Salon and 2 Hot 2 Handle where I won many awards in the Rotary section.

I have a real passion for cars especially Rotarys, I have a open mind towards any car and appreciate the hard work put in. I am currently branch manager at Matamata Repco and been in that industry for 7 years.
