A "strong" earthquake of magnitude 4.7 quake has hit the lower North Island and upper South, rattling buildings in downtown Wellington.
The quake was centred 10 kilometres south of Seddon in the upper South Island and was 22km deep, GeoNet reports.
A GeoNet representative said there had been a few "felt" reports from Wellington but none yet from Seddon.
GeoNet ranked the quake, at 1.45pm, as "strong". The quake would have been enough to shake items off shelves closer to its epicentre.
It was followed a few minutes later by a 2.9 quake in the same area.
Sally Newcome tweeted "The Christmas Tree was doing a dance that's for sure!! "
Hours later a magnitude-4.7 earthquake shook Milford Sound.
GeoNet said the quake occurred at 3.56pm today.
It was located 5 kilometres north of Milford Sound at a depth of 16km.
People from Dunedin to the West Coast reported feeling the quake.
