The New Zealand teams were put to the test at the launch, having to prepare food for the night trussed in gowns and heels.
Mother and daughter team Cathy and Anna advised the Kiwis to always keep their cool. "Keep things in perspective. Sure, it's a competition, there is money on the line, but you walk in with your partner and you walk out with them — so stay friends, stay happy.
"A lot of contestants in the Australian competition struggled with that ... I think we are lucky because we are family."
Youngsters Thalia and Bianca, who were eliminated after their instant kitchen disaster, said the New Zealand teams should just enjoy the ride. "Although you may be in it to win it , remember how fortunate you are to be there."
Christchurch pair Jessie and Ricki said their game plan was to "fake it until we make it".
"Our family was like, 'Can you even cook?' says Jessie. "This is just another chapter in our lives and it will either make or break us."
