"They are not getting the message from New Zealand industry that the opportunities are as good here now or getting better."
Tertiary Education, Skills and Employment Minister Steven Joyce said the view of Australia shown in the survey was an "out of date perception" that was already starting to shift.
Australian growth was decreasing, migration was slowing and more Kiwis were returning.
Employment and Manufacturers Association spokesman Gilbert Peterson said students needed to be matched to areas of demand.
He said "boom times" were returning to New Zealand and there was high demand for skilled employees in building, construction, manufacturing, health, IT and food processing.
"We need to get on and promote the types of careers that are available for our young people because their skills and initiative are going to be in great demand.
"The careers expo itself is an indication of the sort of work we need to do and it's to be applauded, we need to do more of that sort of thing."
Secondary Principals Association vice-president Sandy Pasley, who is head of Baradene Catholic girls' college in Remuera, said a new Ministry of Education programme, Vocational Pathways, was being introduced to schools to help guide students into career paths.
Mr Gillard praised the programme, and said a focus of the expo was to match students' career aspirations to industry demand.
