Hit DIY show The Block NZ is returning for a second season.
More than 1 million people watched last year's finale on TV3, in which siblings Libby and Ben Crawford won $237,000.
Their advice for those wanting to take part in the next season was to prepare for "extreme highs and gruelling lows".
"It will be one of the hardest, yet most rewarding things you'll ever do. Go into it with a tonne of ideas, and a flexible plan," said Libby Crawford.
"Get stuck in, laugh lots and don't sweat the small stuff."
Couples, siblings and friends are invited to sign up at TV3.co.nz/theblock.
