South Auckland police are reassuring their community a child sex offender released into the community is being "effectively managed".
Otara residents have threatened vigilante action after learning the man was living in the area, near three schools and six kohanga reo.
Area Commander for East Counties Manukau Inspector Jim Searle said it was not the role of police to be involved in the placement of offenders in the community.
"(But) police take their responsibility for keeping communities safe seriously," he said.
"We understand that there is anxiety in the community but we would like to assure them that we are working with (the) Probation (Service) to ensure that the person involved is effectively managed."
