The Westpac-McDermott Miller survey, which was conducted from December 1 to 10 last year, also examined consumers' views on their own economic situation.
The survey summarised responses to questions including how respondents view their own financial situation and how they see the economy in general performing.
The Westpac-McDermott Miller Consumer Confidence Index for the Bay of Plenty fell to 105 in the December quarter, from 112 in the previous quarter.
"As was the case in the previous quarter, households in the Bay of Plenty are not particularly optimistic about the prospects for the New Zealand economy and very few think that their own financial circumstances will improve over the next 12 months," Stephens said.
"As a result, households in the region remain cautious about spending with fewer willing to purchase large household items."
