Optimistic Aucklanders have helped push consumer confidence, as measured by the ANZ-Roy Morgan survey, to its highest level for 2 years.
At 118.3 the survey's index is up 3.6 points from December and the highest it has been since June 2010.
But consumer sentiment regularly rises in January and when adjusted for seasonal effects confidence eased from December, though it remains in positive territory.
"We have been here before - every year for the past four years, in fact. Things just tend to fade," said ANZ chief economist Cameron Bagrie.
"I think there is still a fair bit of caution out there amongst households. It reflects two dynamics, [the state of] their balance sheets and a labour market that is not exactly frothy."
