New Zealand at World Geothermal Congress 2026

Events

The 2026 World Geothermal Congress is set to be a monumental event, and New Zealand businesses, organisations and individuals are looking forward to connecting with our international colleagues.

WGC 2026 is being held in Calgary, Canada, with the main conference running from 8th - 11th June, and supplementary events in the days before and after these dates.
