Immigration Minister David Cunliffe told the New Zealand Herald that "Parents and grandparents play a key role in family life. The new policies will make it easier for family from offshore to visit," he said. "Enhanced character and sponsorship requirements ensure a transparent and sustainable family residence programme."

Under the changes, immigrants must be earning around $30,000 a year to sponsor parents to live here, they must also guarantee to support them for five years. Previously there was no income threshold, and support only had to be guaranteed for two years.

Also, people wishing to bring a partner to New Zealand also face a tougher character test.

Other changes include:

* Allowing multiple entry visas for parents and grandparents, making it easier for them to visit family in New Zealand.

* The withdrawal of the existing Family Quota category.

* Establishing quota places for parents (3100-3400), adult children (250-350) and adult siblings (1100-1250).
