The services sector, which accounts for about two-thirds of the economy, slowed in June, although it remains in positive territory with retailing one of the strongest industries.
The BNZ-BusinessNZ performance of services index fell 0.2 of an index point to a seasonally adjusted 56.7 last month. All five sub-indices held above a reading of 50 which separates contraction from expansion.
"Much like the PMI [manufacturing index] did, the PSI exhibited resilience in June, with an index reading of 56.7," said Bank of New Zealand senior economist Craig Ebert.
"There was also accord in the fact the PSI indicated the fastest rate of expansion was occurring in the North Island. As it turned out, June's PSI was barely different to May's outcome of 56.9 and took the three-month average up to a very solid 57.1."
The PSI's sister survey showed manufacturing improved again last month, with all regions expanding, though economists warned a stronger kiwi dollar could weigh on the sector's export earnings.
