The 2023 New Zealand census, which took place on 7 March 2023, was the thirty-fifth national census in New Zealand. It implemented measures that aimed to increase the Census' effectiveness in response to the issues faced with the 2018 census, including supporting Māori to complete the census. It also included new questions on topics such as gender, sexual identity, and disabilities/health conditions. The first Census data was published on 29 May 2024, in a range of data products and services.
Ngāti Porou is a Māori iwi traditionally located in the East Cape and Gisborne regions of the North Island of New Zealand. It has the second-largest affiliation of any iwi, behind Ngāpuhi, with an estimated 102,480 people according to the 2023 census. The traditional rohe or tribal area of Ngāti Porou extends from Pōtikirua and Lottin Point in the north to Te Toka-a-Taiau (a rock that used to sit in the mouth of Gisborne harbour) in the south. The Ngāti Porou iwi comprises 58 hapū (sub-tribes) and 48 mārae (meeting grounds).
Mount Hikurangi features prominently in Ngāti Porou traditions as a symbol of endurance and strength, and holds tapu status. In these traditions, Hikurangi is often personified. Ngāti Porou traditions indicate that Hikurangi was the first point to surface when Māui fished up the North Island from beneath the ocean. His canoe, the Nuku-tai-memeha, is said to have been wrecked there. The Waiapu River also features in Ngāti Porou traditions.
Asian New Zealanders are New Zealanders of Asian ancestry (including naturalised New Zealanders who are immigrants from specific regions in Asia and descendants of such immigrants).At the 2023 census, 861,573 New Zealanders identified as being of Asian ethnicity, making up 17.3% of New Zealand's population.
The first Asians in New Zealand were Chinese workers who migrated to New Zealand to work in the gold mines in the 1860s. The modern period of Asian immigration began in the 1970s when New Zealand relaxed its restrictive policies to attract migrants from Asia.
Ngāpuhi (also known as Ngāpuhi-Nui-Tonu or Ngā Puhi) is a Māori iwi associated with the Northland regions of New Zealand centred in the Hokianga, the Bay of Islands, and Whangārei.
According to the 2023 New Zealand census, the estimated population of Ngāpuhi is 184,470. This compares to 125,601 in 2001, 102,981 in 2006, 122,214 in 2013. and 165,201 in 2018. It is formed from 150 hapū or subtribes, with 55 marae.
Ngāi Tahu, or Kāi Tahu, is the principal Māori iwi (tribe) of the South Island. Its takiwā (tribal area) is the largest in New Zealand, and extends from the White Bluffs / Te Parinui o Whiti (southeast of Blenheim), Mount Māhanga and Kahurangi Point in the north to Stewart Island / Rakiura in the south. The takiwā comprises 18 rūnanga (governance areas) corresponding to traditional settlements. According to the 2023 census an estimated 84,000 people affiliated with the Kāi Tahu iwi.
Ngāi Tahu originated in the Gisborne District of the North Island, along with Ngāti Porou and Ngāti Kahungunu, who all intermarried amongst the local Ngāti Ira. Over time, all but Ngāti Porou would migrate away from the district. Several iwi were already occupying the South Island prior to Ngāi Tahu's arrival, with Kāti Māmoe only having arrived about a century earlier from the Hastings District, and already having conquered Waitaha, who themselves were a collection of ancient groups. Other iwi that Ngāi Tahu encountered while migrating through the South Island were Ngāi Tara, Rangitāne, Ngāti Tūmatakōkiri, and Ngāti Wairangi – all of which also migrated from the North Island at varying times. During the 19th century, hundreds of thousands of Europeans – mostly British – migrated to New Zealand. After European arrival, Ngāti Toa (allied with Ngāti Tama) and Ngāti Rārua invaded Ngāi Tahu's territory with muskets. Some European settlers intermingled with native iwi populations, and today, most families who descend from Ngāi Tahu also have Ngāti Māmoe and British ancestry.
Kiribati New Zealanders refers to New Zealand citizens or permanent residents or others with rights to reside pending move to permanent residency (e.g., by virtue of the Pacific Access Category of immigration (PAC)) who are fully or partially of I-Kiribati descent. According to the 2023 census, 4,659 New Zealanders declared their ethnicity as Kiribati. At present, there may be up to another 1,000 I-Kiribati in New Zealand on guestworker schemes such as the Recognised Seasonal Employment Scheme (RSE). This number has been down since the Covid-19 disruption but is recovering slowly. The Kiribati end of this circular migration was also affected by this disruption.
The New Zealand Census of Population and Dwellings (Māori: Te Tatauranga o ngā Tāngata Huri Noa i Aotearoa me ō rātou Whare Noho) is a national population and housing census conducted by Statistics New Zealand, a government department, every five years. There have been 34 censuses since 1851. In addition to providing detailed information about national demographics, the results of the census play an important part in the calculation of resource allocation to local service providers.
The 2023 census held on 7 March 2023 was the most recent, with the results being released from 29 May 2024 to August 2025.
