Fire-fighters have extinguished a blaze that took hold in a large diesel tank at a coal mine in Waikato.
A truck was refuelling from the 50,000-litre tank at the Glen Coe coal mine in Kopuku, near Maramarua, when the fire broke out just after 3pm on Tuesday.
A Fire Service spokesperson says 40 fire-fighters attended the blaze.
No fuel leaked from the tank and foam used to extinguish the fire was contained on-site, he says.
No one was injured in the incident.
