Respondents report all travel in specified two-day period. See www.transport.govt.nz/ongoing-travel-survey-index/ for more information. |
| Note re 2003-7 and 2004-08 |
In 2009, the NZ Household Travel Survey dataset was revised to ensure professional driver trips were excluded where possible. This has resulted in revision to the 2003-07 and 2004-08 figures above. |
| Definition |
Walking and cycling share of total trip legs by people age 5 and over resident in a Main Urban Area. |
|
A trip leg is a surveying unit of non-stop travel by a single mode for a single purpose. For example, walking to work with a stop at the shop is two trip legs. (Time spent travelling provides an additional and more robust indication of mode share changes over time). |
|
Walk includes walkers, joggers, skateboarders, children in pushchairs and people using wheelchairs. |
|
Cycle excludes mopeds and children’s tricycles. |
|
Main Urban Areas are population centres of 30,000 people or more as defined by Statistics New Zealand. |
|
The NZ Household Travel Survey is designed to capture household travel only and excludes most commercial and freight travel. |
| Frequency |
1989/90 ; 1997/98. From 2003, updated annually with four year moving average. Periods run from July to June so 2003-2007 means July 2003 - June 2007. |
| Disaggregation |
From 2009, regional results will be available |

| Quality of the data |
Survey based. Household Travel Surveys exclude commercial travel, and tend to somewhat underestimate total personal travel. Confidence intervals will be published in late 2009. Response rate (households with full responses from all members): 1989/90=75%; 1997/98=75%; Ongoing survey: 65%-70%. |
