Labour's spokesman on the Environment and Water David Parker defended his party's water royalty policy today on The Country.
Jacinda Ardern revealed that Labour would charge an unspecified royalty for commercial water and use the money to clean up rivers, lakes and streams.
Minister for Primary Industries Nathan Guy has criticised the policy and expressed concern over the potential impact water charges could have on farmers using irrigation.
David Parker refutes this and says Nathan Guy is vastly overstating the potential cost to farming.
