Business confidence has declined for the third month in a row, ANZ's Business Outlook survey has found, though optimists still outnumber pessimists nearly 10 to one.
"The question asked is whether business conditions are going to improve," said ANZ chief economist Cameron Bagrie.
"They are pretty darn good now. More people are simply saying this may be as good as it gets - and they may well be right."
A net 54 per cent of respondents consider business conditions will improve over the year ahead and while that is down 17 points from its peak in February it is still incredibly healthy by historical standards, according to Bagrie.
He said interest rates had risen and a net 89 per cent of respondents expected them to keep rising. The dollar was still high, despite commodity prices - dairy at least - falling and the housing market was levelling out.
