A person is in hospital after being stabbed outside a Countdown supermarket in the Auckland suburb of Mount Wellington

Witnesses reportedly say a homeless person was stabbed in the eye by another homeless person.

A police spokeswoman says they were called to Penrose Road just after 8 this morning.

The victim is in a critical but stable condition in Auckland City Hospital.

An assistant manager of St Pierre's Sushi closed morning as it's behind the Police cordon -- and the news came as a shock.

Police are conducting a scene examination and they're still trying to locate the offender.
