The number of home loans and amount being borrowed has dipped ahead of further lending restrictions, but one mortgage broker says it could be six months before full effects are known.
Weekly figures released by the Reserve Bank show 5668 home loans were approved in the week ending August 12 - down from 6332 in the week ending July 15 - the week before the latest plans to tighten lending were announced.
The amount borrowed also fell from $1.413 billion in the week before the announcement to $1.233 billion in the week ending August 12.
Plans to further restrict lending to investors were announced on July 19 and won't officially come into force until October 1 - but banks have been asked to follow the spirit of the changes already.
There are still a lot of people out there with existing pre-approvals.
