Online employment group Seek says job ads in Australia and New Zealand are down since June.
Chief executive Andrew Bassat said there had been a "consistent but gradual decline in total ad volumes" since June 30.
AAP reports Mr Bassat said in Melbourne on Thursday the decline in volume meant Seek's Australia and New Zealand operations were expected to report flat revenue in the first half of the year compared with the prior corresponding period.
He said the company's performance on both sides of the Tasman in the second half would depend on how willing companies were to hire and the level of consumer sentiment.
At 15.25pm AEDT, Seek was down 15 cents at $6.53.
