Again nearly 4000 people reported feeling the quake, some as far north as Tauranga.
Only a handful of those who felt either quake described it as "extreme". Most classified their experience as "light" or "weak".

One Herald reader reported feeling a quake around midnight in Maketu and more than 200 people reported feeling it with GeoNet.
In nearby Gisborne, locals were preparing for a big one following a Facebook prediction, but Civil Defence has said no one was able to predict an earthquake.

"We hear there's been an earthquake warning put out," said Adele Maynard, sitting in a queue of about 60 cars at the BP east of Gisborne centre with Evan Barbarich.
"On top of the power cut, prepare for everything I suppose. Just to make sure our cars are all ready just in case we have to leave."
This morning some supermarkets have been able to reopen on backup generators.
Tairawhiti Civil Defence Controller Patrick Willock said people have been heading there in a panic.
