The heavy traffic index has come in at a whopping +3.6% m/m change for April.

  • For the y/y, +4.8%
  • March revised to -1.9% from -2.0%

ANZ comments:

  • suggestive of continuing modest growth in Q1
  • Q2 is off to a better start

The 'light' index at +0.2% m/m and +1.6% y/y.

  • suggestive of disappointing Q2 GDP growth
  • annual growth has steadied - indicative of y/y GDP growth declines having run its course

So, yeah mixed signals form the two indexes.

ANZ's 'Truckometer' is an indicator of traffic flows in New Zealand, used as a proxy for GDP growth.
