The ANZ-Roy Morgan Consumer Confidence Index has nudged up 4 points to 114.9 this month, the second consecutive monthly gain.
A reading over 100 indicates optimism.
ANZ senior economist Philip Borkin said confidence was being driven in part by an increase in dairy prices.
"The biggest gains in confidence appear to be in more dairy-aligned regions. Also, mortgage interest rates have continued to fall and regional housing markets are benefiting as Auckland's strength spills over," he said.
But Mr Borkin said there were still plenty of things to be cautious about.
"Unemployment is rising again, dairy incomes are still tight and the global backdrop is concerning," he added.
The index showed that those who believed they were better off financially than last year fell to zero, from 6 in September.
