About us

HydroTrader is a New Zealand company that has been set up to make the trading of water permit allocations easy, anywhere in the country.

While the trading of water permit allocations has been possible since the introduction of the Resource Management Act in 1991, the number of permits to have changed hands has been limited because there hasn’t been an easy way for buyers and sellers to get in touch with one another.

That has now changed with the founding of HydroTrader, a company of experienced and trustworthy local experts who can be trusted to deliver a secure and user-friendly trading experience. 

The founding directors of HydroTrader are:


Dr Anthony Davoren – Managing Director

Tony is a recognised expert in irrigation management, soil moisture monitoring, and surface water resources, with 28 years experience in these fields.  Through his company HydroServices, he and his team carry out soil moisture monitoring throughout the country, as well as providing expert advice to agencies and individuals internationally.

Tony has an MSc (University of Waikato) in Earth Sciences, and a Ph.D. (Washington State University) in Engineering Science. However, it is his practical no-nonsense approach to solving his clients’ problems and boosting production that has seen the demand for his services grow significantly since starting HydroServices in 1983.      


Gus Walkden – Business and Marketing Director

Gus has a wealth of experience in both marketing and high-technology industries, with 28 years experience in the electronics industry, including 11 years at Tait Electronics, New Zealand's biggest privately-owned electronics exporter.

Gus has Masters degrees in both electronics (University of the Witwatersrand) and business administration (University of Canterbury), which he now applies for clients throughout New Zealand through his consulting firm Cornerstone Business Consulting.


Warwick Pascoe – Technical Director

Warwick has seven years experience as an exploration geologist, and a further 23 years in the resource management field, including nine at Environment Canterbury dealing primarily with resource consents for surface water and groundwater.  Warwick now applies his expertise from home for both private and local government clients, having formed ADAM Environmental Ltd in 2005.

Warwick has a BSc (geology) and BSc (Hons) from Victoria University, and it is his job at HydroTrader to provide advice on resource management matters and all aspects of permit trading.
