Last season's winners, the Schreuder family, also won a $20,000 African safari and $10,000 spending money.
TVNZ Head of Content Jeff Latch says he is looking forward to the second series.
"This is a series that really resonated with Kiwis, and season two will be even bigger and better."

The Schreuder family made $190,400 profit on the sale of their Titirangi house, on top of their $100,000 winnings.
The Gourley family earned $143,500 from their sale, while the Wardlaws earned the most at $228,550 profit. However, the Schreuders were declared the winners as they made the biggest profit in percentage terms to the original value of the house.
Winning daughter Karen describes the experience as "a once in a lifetime opportunity".
"As a family we all had such a great time. We can't wait to get on the renovation of our own house."
TVNZ says the show averaged over 375,000 viewers per week, though it faced stiff competition from The X Factor NZ on TV3 during the first weeks of its run. The latter has not been renewed.
Families wanting to take part next series can apply now. The show is set to air in 2016.
