Issues have been identified in the Household Travel Survey (HTS) datasets for the 2023/24 and 2024/25 survey years. Based on information available at this time, approximately 740 household survey records, primarily in the Waikato region, are affected and cannot be validated. These records account for around 60% of the Waikato sample and 5.7% of the national sample.
Further work is being undertaken to confirm the extent of any impacts and determine the appropriate treatment of the affected data. While this work is undertaken, access to the affected datasets is being temporarily suspended, as their validity cannot be assured and may change following completion of the review process.
At this stage, the Ministry is unable to determine the full implications of the issue but will ensure that further information is provided to data users following its review. The HTS remains an important source of information about how New Zealanders travel. However, as a survey-based dataset, it is inherently subject to uncertainty. The Ministry is working to understand the effects of the identified issues and any necessary remediation, particularly for Waikato and any other affected regions, to ensure users are provided with reliable and accurate information going forward.
The information presented here is based on travel reported in the New Zealand Household Travel Survey from a two day travel diary and associated questions. It is weighted at household, person and trip level to represent the population of New Zealand and their travel on an average annual basis.
General and background information on the HTS, including definitions can be found in the tab ‘General information’, above

Total national travel by mode
The total annual travel in NZ for each mode.
Hover over the lines for more detail. The plots can also be enlarged or made smaller and moved using the buttons at the bottom right.
Trip departure time
The share of the trips in the the last 5 years by the time of day of departure.
The share is over the total for the type of day. For example, a share of 3% by females at 11am on weekdays means 3% of all trips done on weekdays are done by females from 11:00am to 11:59am.

Average weekly travel per person
Total annual travel per person, converted to the equivalent over a 7 day week.
Trip length
For every trip travelled, how far people go and how long they take.
Average length and duration of trips by mode.
Distribution of the share of trips by distance and duration.
People tend to remember their travel to the nearest 5 minutes and round accordingly. The graph has been scaled (5 min bins), to smooth this characteristic.
Trip chains
Summaries of trip chains travelled by the number of trips in each chain and the average distance and duration the whole chain.

Travel purpose
Share of all trips by the purpose of the trip.
