Businesses remained optimistic about planning for expansion. However, with labour shortages still very acute, there were signs more businesses were looking to invest in plant and machinery in order to increase output, she said.
Capacity pressures and pricing intentions eased in the June quarter.
Capacity utilisation in the building sector eased from a record 94.6 per cent to 93.8 per cent in June, likely reflecting the effects of softer construction activity earlier this year, Leung said.
"Although we continue to expect that underlying inflation will lift over the next two years, these recent developments add to the case that there is little urgency for the Reserve Bank to begin lifting interest rates," she said.
"We continue to expect the Reserve Bank will hold off lifting the Official Cash Rate until the middle of next year."
