A New Zealand home renovations company is aiming to challenge issues in the renovation market. 

It's worth around $9 a year in New Zealand but the American market's more than half a trillion, which is seen as an opportunity for Kiwi exporters. 

Refresh Renovations founder Jon Bridge told Mike Hosking that no one was doing renovations at scale, and there's been a major problem with budget blowouts. 

He says research indicates nearly a third of money spent on reno's is wasted and around 20% end in disputes.
