RD086 Vehicle kilometres travelled by region (billion km)

More highly populated regions dominate vehicle kilometres travelled.

Definition	Vehicle kilometres travelled on all roads by region by calendar year. 'Other regions' are the total of Waikato, Bay of Plenty, West Coast, and Otago. Available VKT data for these four regions is inconsistent, however, separate estimates are provided in RD087.
Nature of data	Estimate
Primary source	Ministry of Transport analysis based on changes in WoF and CoF odometer readings
Custodian of data	Ministry of Transport
URL	This data has not been previously published.
Frequency	Annual
Disaggregation	By Region
Quality of the data	Regional breakouts of the WoF and CoF odometer data shown here is based on the region where the vehicle was inspected, not the region where the kilometres were actually driven. An alternative source of data on regional VKTs, which does not suffer from this limitation, is the NZTA's Road Assessment and Maintenance Management (RAMM) data, which may be found at http://www.nzta.govt.nz/assets/userfiles/transport-data/VKT.html However, the RAMM data has its own limitations.

RD009 Vehicle kilometres travelled by light vehicles (billion km) and per capita (km)

Both the total vehicle kilometres travelled in light vehicles and travel per capita have increased in recent years until 2018.

Definition	Total road vehicle kilometres travelled (VKT) by for light vehicles in billion kilometres.

Frequency	Annual
Disaggregation	National
Quality of the data	These are the best VKT estimates available, as they are more up to date than the NZTA and TLA RAMM (Road Assessment and Maintenance Management) estimates. RAMM does have the advantage of providing breakouts by region, TLA and road type (state highway/local, open road/urban), so the two approaches are complimentary

RD015 Vehicle kilometres travelled by all vehicles (billion km) and per capita (km)

Both the total vehicle kilometres travelled and travel per capita have increased until 2018.

RD011 Light fleet vehicle kilometres travelled by engine size

Since 2001, vehicle kilometres travelled for vehicles with engines less than 2,000 cc's has changed little, while vehicle kilometres travelled for vehicles with engines larger than 2,000 cc's has a strong growth.

Definition	Light fleet road vehicle kilometres travelled (VKT) by engine size. Light commercial is defined by vehicle type (truck under 3.5 tonnes, van, ute) rather than usage.
Nature of data	Quantitative
Primary source	NZ Transport Agency, Motor Vehicle Register; derived from the change in WoF/CoF odometer readings.

RD016 Vehicle kilometres travelled by vehicle type (billion km)

Travel on the roads has increased with growth in the:

population
vehicle fleet
tourism

Light passenger vehicles dominate travel on New Zealand roads.

Definition	Vehicle kilometres travelled by the types of vehicles. Light commercial is defined by vehicle type (truck under 3.5 tonnes, van, ute) rather than usage

Disaggregation	By vehicle type. For definitions of the vehicle types used, see Vehicle type categorisation
Quality of the data	Good These are the best VKT estimates available, they are far more responsive to fuel price changes than the NZTA and TLA RAMM (Road Assessment and Maintenance Management) estimates. RAMM does have the advantage of providing regional, TLA and road type (State Highway/local, open road/urban) breakdowns, so the two approaches are complimentary.

RD017 Vehicle kilometres travelled by fuel type (million km)

While petrol continues to dominate vehicle kilometres travelled for light passenger vehicles (mainly cars and SUVs), diesel makes up an increasingly large share of vehicle kilometres travelled for light commercial vehicles (mainly vans and utes).

Definition	Road vehicle kilometres travelled (VKT) by fuel type. Light commercial is defined by vehicle type (truck under 3.5 tonnes, van, ute) rather than usage

RD022 Distance travelled by motorcycle by purpose and age group (%)

Motorcyclists aged 15–29 and 45 and over do the majority of their riding for social or recreational purposes, while motorcyclists aged 30–44 do the most riding for work and work-related reasons.

Definition	Percent of person-kilometres travelled by motorcycle by age group (15-29, 30-44, and 45+). Trip purposes exclude 'home'.
Nature of data	Quantitative, survey-based
Primary source	New Zealand Household Travel Survey (Ministry of Transport)
Custodian of data	Ministry of Transport
URL	https://transport.govt.nz/area-of-interest/public-transport/new-zealand-household-travel-survey/
Frequency	Periods run from July to June so 2009-2014 means July 2009 - June 2014.
Disaggregation	By trip purpose and age group
Quality of the data	Survey based. The survey is designed to capture household travel only and excludes most commercial and freight travel, so will underestimate total personal vehicle travel. Response rate (households with full responses from all members): 2003-2014: 65%-70%.
Next Update	To be determined
