Goldmine (but not mine)
On our drive to Withianga we stopped at the Karangahake goldmines. “In their heyday (1883-1933) the Karangahake mines were among the largest of their type in New Zealand. Together (…) they produced 4.000.000 oz of gold bullion.” (Source: information table at Karangahake). Now it´s a historic adventure site, where you can explore the leftovers: remaining foundations, tunnels, kilns, tramways and more.
