The value of total housing finance rose 0.8 per cent to $33.3 billion in June, seasonally adjusted, the Australian Bureau of Statistics said on Wednesday.
The rise was driven by a 1.6 per cent boost in the value of loans for investment housing, while owner-occupied housing loan approvals increased by 0.3 per cent.

"The numbers will be disappointing for regulators looking for a more material slowing in investor activity, although the full impact of macroprudential measures has yet to come through," he said.
The number of first home buyer commitments, as a percentage of the total home loan approvals, rose to 15 per cent in June, from 14 per cent in May.
