Demographics

The 2023 Census recorded 23,172 males and 24,282 females in Whanganui, with 162 people identifying as another gender, living in 18,909 dwellings. Whanganui’s median age of 42.9 years is notably higher than the national median of 38.1, reflecting an older population profile than the main urban centres.

53.4% of respondents identified as having no religion. The most common employment industries are healthcare and social assistance (14.3% of workers) and manufacturing (13.2%) — a combination reflecting both the city’s service sector and its production economy.

Income and Employment

The median individual income in Whanganui was $32,500 at the 2023 Census, compared with the national median of $41,500. This gap is partly attributed to the industry mix, with fewer high-salary professional and finance sector roles compared with Auckland or Wellington. Whanganui’s lower cost of living and housing affordability — house prices remain well below main centres — partially offset the income differential for residents.

Population Growth

Whanganui’s population grew by approximately 13% between 2013 and 2023 — from around 42,153 to 47,619. This reversed a period of stagnation in the early 2000s. Growth has been driven by internal migration from larger cities, relatively affordable housing, and improved cultural infrastructure including the redeveloped Sarjeant Gallery and the city’s UNESCO City of Design status.
