Existing safety rules do cover dam construction, but not their maintenance or operation.Farmers say the new rules will cost them a lot as they have to get their dams checked. And Irrigation New Zealand - which represents farmers and growers, says the threshold for what is considered a large dam under the proposed regulations is way too low. Kathryn speaks with CEO Elizabeth Soal, Otago Federated Farmers President Simon Davies and Peter Amos, Managing Director of Damwatch Engineering.

11:30 A haircut - and a friendly ear

Matt Brown is a barber - but he does so much more than cut hair. After the Christchurch earthquakes set up a barber shop - in a shed in his backyard. He doled out some sweet styles and soon developed a reputation as an artist. But his business, My Father's Barbers, evolved into something more than just a barbershop. It's a safe space where men can open up about the issues that are affecting them. Matt talks to Kathryn about what it's like to build such trust with your clients. He's also delivering a talk at TEDxChristchurch on Sunday 25 August at the Christchurch Town Hall.
