Sumner is a small suburb in Canterbury with a population of 3,411 and a median age of 46. Median personal income is $51K per year. The main ethnic groups are European, Māori, Asian. Canterbury population estimates moved +1.6% in the year ended June 2024, after averaging +1.9% a year from 2018 to 2023, which should be read as a broader regional movement backdrop rather than suburb-level migration precision. The resident employment base moved from 1,908 in 2018 to 1,920 in 2023 (+0.6%), which should be read as a census-to-census employment backdrop rather than a live jobs series. Te Waihanga's December 2025 Pipeline snapshot tracked over 12,000 NZ infrastructure initiatives, with more than 2,700 under construction and transport taking 52% of projected 2026 pipeline spend, which should be read as a broader national delivery backdrop rather than a suburb-specific project list.
Canterbury population estimates moved +1.6% in the year ended June 2024, after averaging +1.9% a year from 2018 to 2023. Read that as a broader regional movement backdrop, not suburb-level migration precision.
The resident employment base moved from 1,908 in 2018 to 1,920 in 2023 (+0.6%, +12). Median personal income is $51K a year. Read this as a stable resident employment-base backdrop across two census snapshots, not a live jobs tracker.
Te Waihanga's December 2025 Pipeline snapshot tracked over 12,000 infrastructure initiatives from 130 contributors, with more than 2,700 under construction and $12.4b of 2026 spend projected in transport (52% of total pipeline spend). There is no matched local transport-stop count here, so read the infrastructure signal as broader NZ delivery context only. That still helps frame future delivery conditions, but it is not enough to infer a nearby catalyst on its own.
This page combines Stats NZ, MBIE, MoE, GTFS, and official service datasets. Check the data-status panel before treating every metric as equally fresh.
- Renters and buyers want to know if the suburb looks affordable before diving into charts.
- Families want a quick read on schools, deprivation, and local service coverage.
- Researchers want one page that ties Census, rent, transport, and approvals into a single suburb brief.
NZ suburb pages combine Stats NZ, MBIE, MoE, GTFS, and pinned service coverage. The key difference is that some items are direct feeds, while others are fallback or snapshot layers.
Treat current rent as a decision input, not as a guaranteed market quote.
This is a trusted coverage layer, but it is still a pinned snapshot rather than a live facility API.
It is good for stop presence and local network context, but not a guarantee that every operator or schedule is equally current.
