Mike Allen - Board Member

As we all recognise, these are challenging times for the energy sector and the geothermal industry more broadly. While Mike have been associated with geothermal activities for more than 40 years, much of his experience has been in helping deliver New Zealand experience and expertise into international projects. The establishment of Geothermal New Zealand Inc (GEONZ) in 2012 provided a platform to explore a more substantial role for the NZ industry overseas: though this has had mixed results, Mike believes it continues to help maintain our position in a number of markets, reinforcing contacts at industry, project and government levels. He also has involvement in the broader renewable energy sector through IRENA and programmes for MFAT and can offer a pragmatic view of how geothermal fits within this wider sector.

Over the last 18 months Mike has had the opportunity to work closely with the New Zealand industry in putting together a national presence for the WGC and through these efforts we have strengthened the connection between NZGA and GEONZ. He has been impressed with the reinvigoration of NZGA activities that the current board has brought to bear and this will ensure strong support for the industry going forward. His interest in joining the board is to reinforce this renewed approach of the NZGA, offer his international commercial experience and connections and ensure that the membership continues to be provided with personal and business development opportunities as appropriate.
