More overstaying migrants have been found to be living in inhumane conditions. 

Several overstayers have been found in a backyard shantytown in West Auckland, living in makeshift sheds and a dilapidated caravan.

The Migrant Exploitation Relief Foundation has since filed a complaint about this case to Immigration New Zealand- and Auckland Council plans to investigate.

Foundation trustee Casey Costello says it's important that these cases of migrant exploitation are being brought to light.

"The circumstances are sad and tragic, but we have this underbelly to our workforce that is here illegally - we're not trying to protect the fact that there's illegal conduct going on - but we also want to get these investigated."
