The head of Managed Isolation and Quarantine says The Wiggles haven't stolen any quarantine beds from desperate Kiwis. 

There's concern over the child's music group being granted space in our facilities for their upcoming tour.

Returnees must now wait until June to be allowed home and emergency requests are often being denied.

MIQ Head Jim Bliss told Heather du Plessis-Allan he signed off on the decision, which will take 12 contingency spots.

"We were very mindful that we didn't take any vouchers available for Kiwis to use to come home, and also that we didn't take any of our emergency allocation."

The entertainers got approved to enter the same day Kiwi Trev Ponting, who is dying in Japan with brain cancer, was told he couldn't come home.

The decision was later reversed after it was raised in the media.

Bliss says he's sympathetic to Ponting's situation.

"We have an urgent review process in place if people want to appeal our decision. So Mr Ponting urgently asked us to review the decision, and we did as an exceptional circumstance."

Ponting's situation had to be deemed "exceptional" - because his request didn't match MIQ's "emergency" criteria.
