TradeMe jobs head Peter Osborne said the number of listings nationwide was up 19 per cent on the same period last year, with growth in all regions.
"Growth in listings has been very strong, despite a Budget that had a cooling effect on the number of jobs advertised in May," he said. "We're hearing plenty of optimistic reports from recruiters and employers, and the majority are planning to keep on hiring, too."
Improved domestic opportunities also contributed to the lowest-ever level of migration to Australia in May, Mr Osborne said.
Demand for skilled workers was still high, with candidates in IT, engineering, construction and legal the most difficult to source.
However, the Statistics NZ household labour force survey showed the employment rate in Wanganui and Manawatu - the percentage of people employed in the working-age population - was 59.2 per cent in the March quarter, down from 61 per cent a year earlier.
