Next January's Pask Great Long Celebration dining and wining experience at the Marine Parade gardens will feature some extra culinary classes with the aid of the 2014 Masterchef winning duo Kasey and Karena Bird.
"It's marvellous to have them on board," Napier Inner City Marketing manager Meg Rodel said.
"They will help design the menu along with Dish Catering for the event which is great - it's very exciting."
The sisters took out the latest series of Masterchef back in May and are planning a book as well as a "foodie tour" around New Zealand, and eventually the world.
They have been in constant demand at food celebration events.
