It's been exactly a week since the government announced its best efforts on improving freshwater- swimmable lakes and rivers in 90 percent of the country in just over two decades. Massey University's Nigel French says what we need to be asking now are three key questions: "Is there shit in the water? Is it dangerous shit ? Where has it come from?" Professor Russell Death, a specialist in freshwater ecology, also at Massey, says we should be more ambitious and better value the health of the ecosystem of our waterways.
