The Team Plunket challenge has seen Unison workers leave their desks to fight it out in the kitchen for the Unison Healthy MegaChef.
Marketing coordinator Jamie Lee Patchett said the competition was run as part of the company's wellness programme Amp'd.
The winning entry was Megan Allan's Super Energy Brown Rice Salad.
"MeganAllan wrote the winning recipe but she had her colleague Kate Silvester put it together whilst she was away running a marathon in Australia - it was delicious."
Team Kepka Builders are pitched against Team Speight's Ale House in the the Team Plunket challenge to see whose players can raise the most funds for the new Onekawa Plunket Centre centre.
The Team Plunket business player who raises the most money wins an Amazing Race corporate package for 20 people from the Kiwi Adventure Trust.
Like the TV show, the winning group will be divided into teams and race to complete challenges, earn rewards and score points.
All entrants will be in to win spot prizes donated by Sharpies Golf Driving Range, Speight's Ale House, Campbell's Bakery and OnTrack Adventures.
The new Plunket centre will be a "one-stop shop" in Onekawa, so families can easily access all Plunket services.
Facilities will include a parents' centre, nurses' clinic, playroom, parenting education classes, family-friendly cafe, toy library and car-seat rental.
A thank you and prizegiving for competitors will be held at Speights Ale House in Ahuriri on July 21.
