1. Te Radar: The kooky Kiwi comedian has had plenty of telly presenting experience, but it's usually in more light-hearted, sometimes surreal fare like Across the Pacific. There's no doubt he can do the more serious, doco stuff, but they'd have to give him a conservative, McCloud-style haircut, and that could be a sticking point.
Rating: 4/10
2. Judy Bailey: She's only wheeled out once a year as the host of Maori TV's Anzac Day coverage, so she's certainly got time on her hands. She also has that nice, calm, motherly appeal, a potential voice of reason when faced with a traditional Kiwi bloke's DIY disaster, so she could be just the ticket.
Rating: 9/10
3. John Hawkesby: With his everyman demeanour and ability to get along with people from all walks of life, there's potential for sure. But 'Six Million Dollar John' hasn't been on TV for aaages. And, what with his love of wine, he'd probably demand every homebuilder include a massive wine cellar.
Rating: 7/10
4. Miriama Kamo: Has an unbeatable background in current affairs thanks to her role on TV One's Sunday. She's untested in light-hearted fare, but she does have experience building her own weird home, with this Waiheke Island bach, so she's definitely a candidate.
