National Traffic Volume

After a second full week at level 2, we’re seeing continued steady growth in traffic volumes week on week.


Auckland was the city with the most dramatic increase in traffic as we moved from level 3 to level 2 – shooting from 56% to 79% week on week.  What we see after a full week at level 2, is much slower growth, an increase of only 3%.


This pattern has not been reflected in the other main Mets, with an average of 15% additional traffic back on the roads week on week (and some climbing to 90% of pre-Covid-19 volumes):

  • Wellington up from 60% to 79%
  • Christchurch up from 71% to 91%
  • Hamilton up from 72% to 93%
  • Dunedin up from 72% to 87%

With many businesses continuing to transition their workers back into workplaces, we expect traffic volume numbers to continue to increase steadily over the following weeks and months.


The data for this report is sourced from NZTA and Auckland Transport, as it is critical to OMANZ and its members, that this data is the most accurate and comprehensive view possible and from a trusted source. Data from these two sources have been blended to provide insight and a representative snapshot of the weekly travel behaviour of New Zealanders as we transition through the Covid-19 alert levels.
