Northland is the fastest growing region in New Zealand, with the population increasing by 18.1 percent over five years
to 179,076, according to 2018 Census figures, Stats NZ said today.
Northland’s growth is followed by the Bay of Plenty, up 15.2 percent to 308,499, and Waikato, up 13.5 percent to
458,202. The West Coast was the only region to decline in population (down 1.8 percent since 2013 to 31,575).
“While Auckland had the largest population increase between 2013 and 2018 (over 156,000 people), regions around Auckland
are growing at a faster rate, with Northland, Bay of Plenty, and Waikato leading the way,” census general manager Kathy
Connolly said. “The 2018 Census counts reflect trends shown in the Subnational population estimates: At 30 June 2018 (provisional)
and will be used to update these estimates in March 2020.”
The census found that New Zealand’s census usually resident population count in March 2018 was 4,699,755, an increase of
10.8 percent since the 2013 Census. A third of New Zealanders (1,571,718) live in the Auckland region, with the
population there increasing by 11.0 percent in the five years since the 2013 Census.
“Auckland’s population is almost three times that of the country’s next most populous region, Canterbury, which has a
population of just under 600,000,” Ms Connolly said.
“The census counts indicated that 60.9 percent of New Zealand's population growth since 2013 was in the four
northernmost regions, and these regions account for over half (53.6 percent) of New Zealand's population.”
As with the 2006 and 2013 Censuses, the 2018 Census found that three-quarters of the population lived in the North
Island. Although the South Island had 100,137 more people than in 2013 (a 10.0 percent increase), the North Island
population increased by 357,504 (11.0 percent).
Territorial authorities and Auckland local board areas
Despite growth being stronger in the northern regions, the territorial authority areas experiencing the highest rates of
population growth since the 2013 Census were Queenstown-Lakes (up 38.7 percent to 39,153) and Selwyn (up 35.8 percent to
“The North Island territorial authorities experiencing the strongest population growth rates were those bordering
Auckland, with Kaipara to the north increasing by 20.6 percent and Waikato to the south by 19.3 percent. Hamilton city
and Tauranga city also experienced large population increases,” Ms Connolly said.
A similar pattern could be seen in the Auckland local board areas. All Auckland local board areas grew, with the
exception of the small Great Barrier area. The fastest growth was in the south (Papakura up 26.3 percent) and north
(Rodney up 21.0 percent) of Auckland.
About the 2018 Census dataset
We combined data from the census forms with administrative data to create the 2018 Census dataset, which meets Stats
NZ’s quality criteria for population structure information.
We added real data about real people to the dataset where we were confident they should be counted, but they hadn’t
completed a census form. We also used data from the 2013 Census and administrative sources, and statistical imputation
methods to fill in some missing characteristics of people.
The independent External Data Quality Panel has endorsed the statistical approaches used by Stats NZ to mitigate
The census usually resident population of an area is a count of all people who usually live in that area and were
present in New Zealand on census night. These census counts are the basis for, but are different to, population
estimates and projections. From March 2020, Stats NZ’s population estimates and projections will be updated to
incorporate 2018 Census and 2018 post-enumeration survey results. Expected updates for population statistics 2019–20
includes more information about population measures.
