On the programme today, we speak to Associate Professor Sergio Biggemann (Marketing Department, University of Otago Business School) on the Government's plan to crack down on the supermarket duopoly, which he says will have little impact on the costs consumers are facing at the till. We also talk with Emily McEwan, Dunedin City Council Policy Planner, on the DCC's latest changes to the Dunedin City Second Generation District Plan, allowing for greater housing density in the city.
