The magnitude 6.5 quake has resulted in more than2000 claims being filed with the Earthquake Commission.
Seismologist Caroline Holden said, as with the February 2011 quake in Christchurch, the number of aftershocks was not unexpected.
She said the main difference is that in Wellington only about 10 of the 1900 aftershocks would have been felt, but thousands were felt in Christchurch.
GNS has deployed extra seismic intruments in Marlborough to record the aftershocks.
