Based on its magnitude, the fault that was active during the quake ruptured along a surface of approx. 1259 km
2 (=486 sqare miles) as a first-order estimate. The length of the rupture zone thus was probably around 61 km (38 mi).
Aftershocks typically occur during the weeks, months or even a year following the quake at or near the same fault, at distances of up to approx. two times the length of the rupture zone.
The often broadly linear arrangement of aftershock epicenters encompasses the rupture zone of the main shock (check on the map below to verify).
Recorded aftershocks, latest first (2777 quakes):
Late on Friday the EQC Earthquake Commission had only received 27 claims from across the North Island, a spokesman said. The extent of the reported damage is not yet known and assessors are working with customers to resolve the claims.

Coastal residents evacuated to higher ground after tsunami warnings. In Northland where the tsunami waves were expected to be worst, emergency workers and the public reported little damage. Northland Civil Defence spokesman Murray Soljak said he had not heard any reports of damage, although his team would often only be alerted if there was a threat to life as well.
It was Graeme and Pauline Summerby's dog, Monty, that felt it first. They, along with tens of thousands of others, were rattled from their sleep at 2.30am in what would be the first scare of many during the day.

4.8 quake 5.7 Km ENE of Skógar, Iceland, 4 Mar 2021 7:09 pm (GMT +0)
An earthquake of magnitude 4.8 occurred early evening on Thursday 4 March 2021 at 7:09 pm local time near Vik, Mýrdalshreppur, South, Iceland, as reported by the Icelandic Met Office (IMO).
According to preliminary data, the quake was located at a very shallow depth of 8.5 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
