A 4.8 magnitude earthquake has struck near Hokitika.
The earthquake was four kilometres deep and struck at 1.12pm about 60km south of Hokitika, Geonet says.
It was one of three shallow earthquakes in the South Island within 15 minutes on Tuesday afternoon.
The first 4.5 magnitude quake hit at a depth of five kilometres, 60km south of Hokitika at around 1.05pm.
The 4.8 magnitude quake hit the same spot seven minutes later.
The two West Coast quakes came minutes after a weak 3.8 magnitude earthquake hit 65km north-west of Methven at a depth of 15 kilometres.
A GeoNet scientist told Newshub it's possible more quakes could come and they were "keeping an eye on it".
