We can't help but wonder...

3News reports:

Opposition parties say the visa fraud that allowed 231 Chinese students to get into New Zealand must be fully investigated.

Labour and New Zealand First are also calling for tighter rules around student visa applications following yesterday's revelation that agents in Beijing were behind fraudulent applications filed with Immigration New Zealand.

Authorities are asking the students to identify themselves and say they might not know they hold visas granted on the basis of falsified qualifications and bank statements.

Immigration New Zealand says 60 students are in the country unlawfully because their visas have expired and 171 have valid visas but could be liable for deportation depending on their circumstances.

A total 279 were involved in the scam but 48 have either left or haven't arrived yet.

There does indeed seem to have been a serious, determined and systematic assault on New Zealand's immigration laws here, and that does merit further investigation.

But we can't help but wonder; at what hour did Raymond Huo from Labour and NZ First leader Winston Peters have to get out of bed to get their calls for an inquiry in before the Greens did?
