Rumblings were felt in Takanini, Auckland, where Sabrina Papps told the Herald she and her family had just enjoyed a meal out when their car began to shake.
"My mother went to check the engine, it stopped and nothing was there, then returned and heard the same loud rattle again after about 30 secs," Papps said.
"Amazing to feel it from so far away! Turns out we never heard that sound prior or after the quake as the car is up to date with no issues."
Geonet's quake notification on Twitter prompted responses from around the country, with one saying "massive jolt in Nelson" and another from Upper Hutt saying it was "more like a truck going past".
GNS Science seismologist John Ristau said the quake was one of four in New Zealand with a magnitude larger than 5.5 over the past year and was unlikely to produce large aftershocks.
"Deeper earthquakes like these don't tend to produce significant aftershocks. Further earthquakes are always possible, but unlikely."
