With last year's title holder Jared MacKenzie now running in the main Wifiplus KZ2 class, rally driver turned karter Andrew Hunt has taken over as the driver to beat in Aarque Group DD2 Masters.
However, Hawke's Bay racer Tim Loughran is just 11 points adrift in second place and just nine points separates the next six drivers, amongst them Speedway Super Saloon star Terry Corin from Tauranga and Rotorua's own Darren Aislabie.
This weekend also sees the Masters field bolstered by the return of Auckland driver Leo Bult and Glenn Tremain from Tokoroa.
Aarque Group KZ2 Restricted has also seen an influx of new faces this season. The man who has dominated the class for the past two years, Aucklander Garry Cullum, continues to lead the points standings, but was pipped for pole in qualifying by Shaun Anderson and conceded a win to Anderson's Wellington travelling mate Jamie Pollock in one of the heats at the second round at Te Puke.
A breakthrough round at Te Puke sees series regular Gerhard Benadie tied for second place in the points standings with class new-face Regan Hall, while fellow Aucklander Aaron Wooley is one point back in fourth and Shaun Anderson another single point adrift in fifth.
Interest in the restricted class is also increasing, with three more drivers, Kevin McDonald, Andrew Jackson and Joshua Melrose (all Auckland) making their series' debut at Rotorua.
There will be action on track at The Rock FM Raceway from 9am on Saturday and Sunday and spectators are welcome.
The Rotorua round of the 2017 Molecule ProKart Series is the third of six with the fourth in Auckland at the end of July and the fifth and final at Hamilton in August.
