A row has broken out in New Zealand, where thousands of dollars of taxpayers’ money has been spent on importing mud from South Korea for a music festival. Five tonnes of mud powder from Boryeong in South Korea, costing NZ$90,000 (US$68,000; £51,600) have been imported for Rotorua’s forthcoming Mudtopia festival and is said to represent good value for money. The cost is expected to be recouped from ticket sales.
