This is a list of large earthquakes that have occurred in New Zealand. Only earthquakes with a magnitude of 6.0 or greater are listed, except for a few that had a moderate impact. Aftershocks are not included, unless they were of great significance or contributed to a death toll, such as the M 6.3 2011 Christchurch earthquake and the M 7.3 aftershock to the 1931 Hawke's Bay earthquake.
Earthquakes occur frequently in New Zealand as the country is situated in the collision zone between the Indo-Australian and Pacific tectonic plates, part of the Pacific Basin Ring of Fire, where many earthquakes and volcanoes occur. Most events occur along the main ranges running from Fiordland in the southwest to East Cape in the northeast. This axis follows the boundary between the Indo-Australian and Pacific plates. Large earthquakes are less common, where the plates are not subducting and the forces are accommodated in different ways.
The largest city within the highest-risk zone is the nation's capital, Wellington, followed by Napier then Hastings. All these cities have experienced severe earthquakes since European settlement. About 14,000 earthquakes occur in and around the country each year, of which between 150 and 200 are big enough to be felt. [2] As a result, New Zealand has very stringent building regulations. The 1929 Murchison earthquake and 1931 Hawke's Bay earthquake led to the development of stricter building codes in New Zealand from 1935. [3]
Quite early on, European settlers were faced with the reality of earthquakes in their new home. On 26 May 1840, the new settlement at Port Nicholson was struck by the first of a number of earthquakes and tremors. [4] Early settlers learned fairly quickly the importance of using appropriate building methods in an earthquake-prone country. The 1848 earthquake, centred in Marlborough, caused great damage to the brick and masonry buildings in Wellington, and the city was rebuilt mainly in wood; consequently it suffered comparatively little damage in the 8.2 magnitude earthquake of 1855, which lifted the land 2–3m. [5] Many buildings in Hastings and Napier were damaged in the 1931 Hawke's Bay earthquake. New building regulations meant that any new buildings constructed afterwards attempted to take earthquake shaking into account in building design. [5]

Seddon is a small town in Marlborough, New Zealand. It is located 25 kilometres (16 mi) south of Blenheim, close to the mouths of the Awatere and Blind Rivers and the Lake Grassmere salt works.
The 2007 Gisborne earthquake occurred under the Pacific Ocean about 50 kilometres (31 mi) off the eastern coast of New Zealand's North Island at 8:55 pm NZDT on 20 December. With a moment magnitude of 6.7 and maximum Mercalli intensity of VII, the tremor affected the city of Gisborne and was felt widely throughout the country, from Auckland in the north to Dunedin in the south.
The 2009 Dusky Sound earthquake was a Mw 7.8 earthquake that struck a remote region of Fiordland, New Zealand, on 15 July at 21:22 local time. It had an initially–reported depth of 12 km (7.5 mi), and an epicentre near Dusky Sound in Fiordland National Park, which is 160 km (99 mi) north-west of Invercargill. It was the country's largest earthquake magnitude since the 1931 Hawke's Bay earthquake, but caused only minor damage and there were no casualties. A tsunami accompanied the event and had a maximum measured run-up of 230 cm (91 in).
The 2010 Canterbury earthquake struck the South Island of New Zealand with a moment magnitude of 7.1 at 4:35 am local time on 4 September, and had a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. Some damaging aftershocks followed the main event, the strongest of which was a magnitude 6.3 shock known as the Christchurch earthquake that occurred nearly six months later on 22 February 2011. Because this aftershock was centred very close to Christchurch, it was much more destructive and resulted in the deaths of 185 people.
The June 2011 Christchurch earthquake was a shallow magnitude 6.0 Mw earthquake that occurred on 13 June 2011 at 14:20 NZST. It was centred at a depth of 7 km (4.3 mi), about 5 km (3 mi) south-east of Christchurch, which had previously been devastated by a magnitude 6.2 MW earthquake in February 2011. The June quake was preceded by a magnitude 5.9 ML tremor that struck the region at a slightly deeper 8.9 km (5.5 mi). The United States Geological Survey reported a magnitude of 6.0 Mw and a depth of 9 km (5.6 mi).
The 2013 Seddon earthquake measured 6.5 on the Mww scale and was centred in New Zealand's Cook Strait, around 20 kilometres (12 mi) east of the town of Seddon in Marlborough. The earthquake struck at 5:09 pm on Sunday 21 July 2013 at a depth of 13 kilometres (8 mi), according to GeoNet. The United States Geological Survey also measured the quake at 6.5, at a depth of 17 kilometres (11 mi). The quake caused moderate damage in the wider Marlborough area and Wellington, the nation's capital city 55 kilometres (34 mi) north of the epicentre. Only minor injuries were reported. Several aftershocks occurred during 21–29 July.
The 2013 Lake Grassmere earthquake was a magnitude 6.6 earthquake that occurred at 2:31:05 pm (NZST) on Friday 16 August 2013. The epicentre was located about 10 km south-east of Seddon, under Lake Grassmere, with a focal depth of 8 km. The earthquake caused significant land damage in the local area, with landslips blocking roads, including the main highway between Blenheim and Christchurch. Buildings in Seddon were damaged, with some being declared uninhabitable. The earthquake was widely felt in both the North and South Islands of New Zealand.
The 2014 Eketāhuna earthquake struck at 3:52 pm on 20 January, centred 15 km east of Eketāhuna in the south-east of New Zealand's North Island. It had a maximum perceived intensity of VII on the Mercalli intensity scale. The magnitude 6.2 earthquake was followed by a total of 1,112 recorded aftershocks, ranging between magnitudes 2.0 and 4.9.
The Hikurangi Margin is New Zealand's largest subduction zone and fault.
The 2016 Te Araroa earthquake was an earthquake measuring 7.1 on the moment magnitude scale that occurred at 04:37:55 NZST on 2 September 2016. The epicentre was located 125 km (78 mi) north-east of Te Araroa off the East Cape of the North Island of New Zealand with a focal depth of 22 km (14 mi). The earthquake was widely felt throughout the North Island and in the upper South Island. There were no reported casualties, and buildings predominantly suffered only a little bit of damage.
The 2016 Kaikōura earthquake was a Mw 7.8 earthquake in the South Island of New Zealand that occurred two minutes after midnight on 14 November 2016 NZDT. Ruptures occurred on multiple faults and the earthquake has been described as the "most complex earthquake ever studied". It has been subsequently modelled as having a megathrust component set off by an adjacent rupture on the Humps Fault. It was the second largest earthquake in New Zealand since European settlement.
The 2021 Kermadec Islands earthquakes were a series of earthquakes with magnitudes of 8.1 and 7.4 that occurred at 19:28:31 UTC on 4 March 2021. The epicentres were located southeast of Raoul Island in the Kermadec Islands, part of the New Zealand outlying islands. The main magnitude 8.1 earthquake was preceded by a magnitude 7.4 foreshock and followed by a magnitude 6.1 aftershock. A separate, unrelated magnitude 7.3 earthquake occurred off the coast of the North Island of New Zealand, approximately 900 km to the south, several hours before the main quakes. More than a dozen aftershocks exceeded magnitude 6.
