The family of the officers shot by an offender in West Auckland are very shaken up

At a routine traffic stop this morning in Massey, one officer was shot dead, and another remains in hospital in a serious condition.

Police Association president Chris Cahill says it's not something the family members expected to hear - even though they are aware of the risks.

He says they are feeling it - but they are also feeling the support from the Police community.

Police Commissioner Andrew Coster is expected to give an update on the incident shortly.
