Geonet said the quake measured 6.5 (REVISED), 10km south east of Seddon at a depth of 8km. Initial reports said the quake was 6.9.
People in Wellington said the quake was very strong and all train services in the region have been cancelled. It was felt as far away as Gisborne, Auckland and Hamilton
A magnitude 5.7 aftershock centred 5km southeast of Seddon and 8km deep hit about six mintues later.
Public safety authorities have been inundated with calls. The quake struck at 2:31pm local time.
Reaction from residents on Twitter indicated the quake was larger than the one that rocked the city last month.
