Mackenzie finally made his long-awaited WSBK bow at his home circuit with his regular McAMS Yamaha squad after an injury picked up in BSB pre-season testing forced him to skip his originally-planned debut at Assen.
The 26-year-old qualified 13th for Saturday's opening race of the weekend, going on to finish 14th - only around six seconds behind the works Yamaha of Andrea Locatelli and well ahead of satellite GRT machine of Kohta Nozane.
