Over the last four years, congestion has slightly reduced average speeds on state highways in Auckland and Wellington, but there has been little change on local roads. In Christchurch, speeds on both state highways and local roads have actually increased.

Nature of data
|Based on surveys conducted by BECA during the month of March each year. The new methodology (from 2014 onward) involves collecting large volumes of anonymised GPS data. Observed vehicle speeds are distance- and volume-weighted to provide aggregate statistical data for the network as a whole. Up to 2014, a 'floating car' methodology was used, and results are not comparable with the new methodology. The old methodology did not provide separate data for state highways and local roads.|
