Consumer confidence slipped slightly in March the ANZ-Roy Morgan Consumer Confidence survey says.

The company said its measure of consumer confidence slipped 1.8 points to 121.8 in March.

"Despite this fall, the overall level remains positive, with the March quarter average four points higher than the preceding December quarter," the survey's authors said.

The March figure is the lowest recorded this year, but it remains the fourth-highest level to be measured during the recent rebound.

Households are more optimistic about the current situation and less optimistic abut the future prospects.

The proportion of respondents who thought they were better off now compared to a year ago increased by four points but the index figure for expectations in 12 months' time dropped nine points to 120.

A net 20 percent of consumers thought it was a good time to buy a major household appliance, up six points from a month ago.
