Prince Harry and Meghan Markle will be visiting Rotorua on Wednesday and Masterchef winners Karena and Kasey Bird will be cooking for them.
The Duke and Duchess will stop at Ohinemutu for lunch. The Maketu sisters will be using local products and cooking traditional foods, which they cannot be more excited about.
Kasey told the NZ Herald a lot of their helpers in the kitchen would be family.
"It's exciting for us and for everyone involve.
"It's certainly an opportunity you never think you'll get and one we'll certainly look back on and just think 'wow'. The request was for traditional food and food from the local area and that's what we love cooking," Kasey told the New Zealand Herald.
They will be using traditional cooking methods and steam boxes.
"So we are revitalising some of the old cooking techniques and giving our own twist to the foods we grow up on and the foods you find at the marae."
Kasey said they wanted the lunch to have the same feel as any marae function, just with nicer plating.
She said they were really grateful for the opportunity and pleased they had been thought of as the ones to do it.
There will be about 180 guests at the lunch which will include Ngāti Whakaue elders and they only have 35 minutes to eat.
