However, the competition will be tough for Williams who will be up against Auckland rivals Michael Pickens, Brad Mosen, Ryan Baker and Max Guildford and his BSL racing team-mate Hayden Guptill.
Along with Baypark and Western Springs-based competitors, the Midget Car field includes Palmerston North's Shane Dewar and emerging teenage talent Mitch Fabish (Te Awamutu).
The bumper fields entered for the opening night has prompted Baypark Speedway officials to reschedule the initially planned fireworks celebrations till later in the season.
"With such strong fields entering for the first meeting, we have decided to let the racing take priority. The fireworks will happen later in the season," Baypark Speedway operations manager Melissa Webb said.
Super Saloons along with Stock Cars and Youth Mini Stocks complete the opening night race programme.
Racing starts at 6.30pm.
