Police have apologised for failing to send help to an intellectually disabled man and his caregiver after they rang 111.
The pair were sheltering in a locked car from a woman thumping the vehicle and shouting abuse at them.
The abusive woman, 20, shares an IHC house with the man, 51, his partner, a frail 58-year-old, and another female flatmate, 22. All four flatmates are intellectually disabled to varying degrees.
Their caregiver, Sheryl Ritchie, works for IHC's service arm Idea Services. She said the 20-year-old was violent and shouldn't be living in the house as the other residents were afraid of her.
Police have admitted they should have attended an incident at the group's Papakura home after Ritchie dialled 111 from her car.
