Consumer confidence has slumped to its lowest level in nearly three years in this month's ANZ Roy Morgan survey.
The survey's overall index fell six points from June levels and at 113.9 is now below its long-run average of 119.1.
All the survey's indicators deteriorated but the steepest decline was in respondents' view of economic conditions a year ahead. A net 2 per cent expect them to be worse, where a net 11 per cent were still positive last month.
"Economic headwinds have intensified and the impact of weaker dairy prices is beginning to percolate through the regions," said ANZ economist Philip Borkin. "The growth impetus from the earthquake rebuild is fading and global ructions and risks are clear to see."
