Wellington water study could help drought-stricken regions

A group of New Zealand scientists hope the work they have done mapping a Wellington aquifer will help others around the world find new sources of drinking water. Instead of resorting to expensive drilling, the group from NIWA used video footage and acoustic soundings of freshwater flowing out from the Waiwhetu Aquifer under Wellington harbour. The project designer Joshu Mountjoy joins Nights to talk about the research and its potential.
