Despite the number of jobs being advertised being down 26 percent in a year, applications per job ad are at their highest on record, Seek NZ says.
The website's monthly job report showed job ad volumes declined another 4 percent month-on-month, after last month's 3 percent fall.
The volume of job ads fell in all regions apart from West Coast and Hawke's Bay and was driven by Auckland, Wellington and Canterbury.
Seek NZ country manager Rob Clark said despite this, demand for work was at an all-time high.
"Applications per job ad are now at record high levels, meaning there is now more competition for the jobs available than ever before," Clark said.
"We are seeing an increase in the number of applications that are coming from overseas, with the most applications directed at entry level or support services roles."
As the data had a one-month lag, July's figures were compared to June data from the previous year.
Clark said the number of applications per job ad in the manufacturing, transport and logistics, and the community services and development industries increased 24 percent month-on-month.
"Aged and disability support roles saw a 51 percent increase in applications per ad in June alone," he said.
The overall decline in job ads was driven by the manufacturing, transport and logistics, information and communication technology and trades and services sectors.
However four industries, including the administration and office support and sport and recreation volumes sectors, recorded an increase in job ads, Clark said.
