On the 2nd of August 2018, Mr Upton gave an address to the Environmental Defence Society Conference in Auckland.
In his address "Nutrient transport, water quality and modelling: Joining the dots" the Commissioner highlighted three things relevant to water quality that needed improvement. Firstly, a better understanding of nutrient transport in three dimensions across a catchment. Secondly, a better understanding of what models can and can’t do to assist in building that picture. Thirdly, improved communication of what is happening to water quality.
