Overnight house fires in the South Island have left two homes gutted.

A flurry of calls came in to Fire and Emergency New Zealand around 1.15am this morning, alerting them to a house fire off State Highway 6, just south of Greymouth.

The fire itself was visible from nearby State Highway 6, otherwise known as Main South Rd.

The house is believed to be unoccupied.

Meanwhile, five fire crews attended a house fire in Wānaka.

Residents of the Wilkin Rd house were able to get out in time, as yet another flurry of calls were made to Fire and Emergency around 2.30am.

No injuries have been reported.

A Fire Investigator will attend the scene of the Greymouth fire this morning.
