This is the Martha open pit gold mine in Waihi New Zealand. To give you a sense of scale, when the mining is finished it will be flooded to form a 634 foot (195m) deep reservoir above the town of Waihi.
For full disclosure, my airplane ticket was purchased by Air New Zealand and the Tourism New Zealand. Tourism New Zealand also gave me an Explore New Zealand pass which enabled me to take this cruise for free. My transportation has been a camper van provided by Spaceships.
