A Warehouse security guard who called a customer an "arrogant p****" and allegedly made a racist comment because they were white was wrongly dismissed.
Loss prevention officer Margaret Maria Harris was sacked from The Warehouse's Kaikohe store after a complaint from the husband of a customer last February.
The Employment Relations Authority (ERA) said Ms Harris approached the customer, who was standing near a checkout with a dog, and twice asked her to leave because dogs were not allowed in the store.
The guard then followed the customer out to the foyer, where CCTV footage appeared to show a heated exchange, with arms raised. Two Maori wardens intervened and Ms Harris threatened to trespass the customer and call police.
The customer's husband wrote a letter of complaint, alleging Ms Harris had loudly said: "How arrogant!"
