The Miss Frankton Thunder Pin-Up contestants enter in three categories.
The 10 women are allocated to an equal number of photographers and a selection of sparkling custom and high-performance machinery during the Thunder Photo-Rama section.
"In the Photo-Rama we're looking for poise, the girl's ability to listen to the photographer and how they interact with each other."
Principal judge for the Frankton Thunder Photo-Rama is Hamilton professional photographer David Rowe and first prize is a 90-minute photo shoot with Rowe and fellow professional Keith Maynard.
Just after midday, the contestants then head for the main stage and the swim-suit section of the competition, MCd for the fourth year by Tone Parangi.
"Then we do a Best Dressed vote from the crowd. For the the third section the contestants appear in day wear and undergo a short on-stage interview.
"The aim is to allow the audience to get to know the girls better. There's no right or wrong answers. It's about personality," Wakefield said.
Part of first prize is a floral bouquet donated by Frankton business Florist Ilene.
Frankton Thunder also includes the Thunder Ink tattoo competition, $10 entry with funds donated to St Vincent de Paul.
Judging will be by a professional skin artist from My Crazy Life Tattoo in Frankton. A new category this year is New Zealand — tā moko.
Along the street will be 14 market stalls offering a range of life-style products from beard oil to leather goods. New this year is the Steampunk market.
Frankton Thunder will take place in and around Commerce St Frankton, Hamilton, 9am to 3.30pm, Sunday March 10.
