Year 13 students Samuel Heaven and Daniel Moss won with their entree, silverbeet sausage with truffle meringue with silverbeet and nutmeg mousse encased in a mozzarella balloon, and main of chicken roulade with beetroot and lavender gel, fondant potatoes and baby vegetables.
Daniel also won a bronze with first in class, and Samuel won six first in class awards and was the overall secondary school champion.
Samuel said there had been a lot of late nights in the lead-up to the competition, when he would be awake until 2am coming up with ideas.
"We knew the standard was going to be high so we had to really up our game." His parents own the Hawke's Bay chain, Heaven's Bakery.
The most challenging part, Daniel said, had been researching and trying new ideas out to see what would look amazing on the plate.
The final dishes were an "evolution" of about 50 different recipes, with the pair taking elements they liked from each dish to the next.
While there were always things that could go wrong in a live competition, both boys said they were happy with the final dishes.
They will go up against winning teams from other regional finals in the grand final in Auckland on August 30.
