Locations of all public EV charging stations across New Zealand, sourced from charge station owners and operators via inbound API. Connector information groups type, power rating, and status (e.g., 'AC, 44 kW, Type 2 Socketed, Status: Operative, Count: 4'). Available without API signup. Key dataset for understanding EV infrastructure coverage and its relationship to EV RUC policy. Licensed CC-BY 4.0.
Real-time data on events and incidents affecting state highway traffic via the Traffic and Travel Data System API. Five components: live traffic conditions, travel time estimates, event/incident alerts (including weather warnings), camera imagery from 100+ locations, and variable message sign content. RESTful API at trafficnz.info. Data quality improvements applied October 2024. Covers only notable events verified by Waka Kotahi or official sources.
A point-in-time snapshot of approximately 5.8 million vehicles currently registered in New Zealand, updated monthly. Contains 39 fields including make, model, body type, fuel type, fuel consumption (litres/100km), and synthetic greenhouse gas emissions. Vehicle Identification Numbers limited to 11 characters for privacy; owner data aggregated to Territorial Authority level. Many fields are free text — Waka Kotahi has published open-source cleansing code on GitHub. The primary data source for fleet composition analysis and RUC policy modelling.
Four index series used to adjust supplier contract prices as costs fluctuate: bitumen cost adjustment (published monthly), original 1991 infrastructure cost indexes, new infrastructure cost indexes, and public transport cost index. Raw data sourced from Stats NZ, with Waka Kotahi calculating and publishing the bitumen series independently. Indexes fixed quarterly (monthly for bitumen). Relevant context for understanding how transport infrastructure costs feed into road funding decisions.
Household Economic Survey expenditure data broken down by household income group, including all transport spending categories. Shows how transport costs vary as a proportion of income across different socioeconomic groups. Critical for understanding the regressivity of road user charges and fuel excise — lower-income households typically spend a larger share of their income on transport, making this dataset essential for equity analysis of road pricing reform.
Distinct counts of current NZ driver licence holders by region, class (Class 1 cars, Class 6 motorcycles), licence stage (learner/restricted/full), and age bracket. Annual snapshots as at 1 July for financial years 2010–2024. Data reflects registered addresses, not actual locations, and includes overseas licence holders. Small regions (Chatham Islands, Gisborne, Tasman, West Coast) grouped as 'Misc' for privacy. Historical notes: minimum driving age increased to 16 in 2011; COVID-19 affected testing facilities 2020–2022.
Test version of the driver licence holders dataset containing a snapshot of licence holders for July 1–30, limited to current photo licence holders with Class 1 or Class 6 licences. Provided for API testing and development purposes.
Approximately 1.39 million records of heavy vehicle (over 3.5 tonnes) traffic volumes from Commercial Vehicle Safety Centres, updated monthly on the 5th. Data grouped by date and time quarter (0–6, 7–12, 13–18, 19–24), location, lane, axle count, class, and gross weight (rounded to nearest 1,000 kg). Currently covers five centres: Glasnevin, Ohakea, Paengaroa, Rakaia North, and Rakaia South. Records from January 2023 forward. Essential for understanding heavy vehicle movements — the primary users of distance-based RUC.
Summary statistics on driver licence test pass rates for Class 1 learner, restricted, and full licence tests from January 2010 to December 2024. Broken down by region, age bracket, and licence type. Provides insight into new driver entry rates which affect future vehicle fleet growth and RUC revenue projections.
Count of fatal and serious non-fatal injuries in New Zealand by sex, age group, ethnicity, cause, and severity from 2000 to 2024. Causes include motor vehicle traffic crashes alongside other injury categories. Provides the official Stats NZ injury series that complements Waka Kotahi's Crash Analysis System data — useful for understanding the broader road safety context that informs transport investment decisions funded through the National Land Transport Fund.
Interactive dashboard showing all vehicles registered in New Zealand for the first time during the most recent calendar month. Includes a subset of reregistered vehicles with filtering capabilities. Useful for tracking new vehicle trends, EV uptake rates, and fleet composition changes in near-real time.
Approximately 904,000 crash records reported by NZ Police on public roadways from January 2000 onward, updated monthly. Contains 80+ non-personal variables covering crash circumstances, vehicle types, road conditions, weather, and injury counts. Processing times vary: fatal crashes within one working day, injury crashes within 4 weeks, non-injury up to 7 months. Note: 2020–2021 data is incomplete. Licensed CC-BY 4.0. The primary dataset for road safety analysis in New Zealand.
Stats NZ Household Economic Survey data showing household expenditure by detailed category including transport (vehicle purchases, fuel, vehicle servicing, public transport fares, and other transport costs). The primary official dataset for understanding how much New Zealand households spend on transport — a key input for assessing the real-world cost burden of road user charges and fuel excise on household budgets.
Household Economic Survey expenditure data broken down by broad region (Auckland, Wellington, Rest of North Island, Canterbury, Rest of South Island). Includes transport spending categories. Reveals regional variation in household transport costs — important for RUC policy analysis given that rural households typically have higher transport expenditure due to longer distances and fewer public transport alternatives.
2,042 traffic monitoring site records across New Zealand's state highways. Includes site coordinates, average daily flows, heavy vehicle percentage estimates, sensor type, and sampling days. Typical error margins of 2–5% (higher at congested sites). Classification capabilities vary by equipment type, and non-continuous site counts are adjusted using continuous site values. The reference dataset for understanding where and how New Zealand measures road usage.
REST API service providing real-time traffic conditions, travel times, road events, and incidents across the national highway network. Extracted from the Traffic and Travel Data System. Designed for integration into third-party applications, traffic management systems, and real-time dashboards.
Overview of road restrictions for 50MAX heavy vehicles across New Zealand, including bridge weight limits and restricted routes. 50MAX permits allow qualifying trucks up to 50 tonnes on approved routes. This geospatial dataset maps where restrictions apply — directly relevant to heavy vehicle RUC operations and freight route planning.
Feature service API providing daily-updated traffic volumes from state highway telemetry count sites, by vehicle type. Same underlying data as the CSV download but accessible via REST API for programmatic access and integration into dashboards or analysis tools.
Public web map showing Annual Average Daily Traffic (AADT) volumes for state highways. Data is presented in two ways: at individual count sites and as estimated traffic volumes between sites. Provides a visual overview of traffic demand across the entire state highway network.
Carriageway (road segment) attribution supplied by Road Controlling Authorities and councils, with point geometry marking the start and end of each segment. Updated monthly. As of the October 2018 release, 76% of RCA attribution was included — coverage continues to expand. The foundational spatial reference dataset for New Zealand's road network.
