One of the men signed the seal across the box and then they distracted the salesperson for long enough to remove the ring. When they failed to return to the store, staff opened the box and discovered the ring was missing.
Later that day the men went to a Michael Hill Jewellers store in central Auckland and asked for an "expensive diamond ring".
Staff at the store found such a ring at their Manukau store and, believing the men were legitimate "sales professionals", drove them to view the ring they wanted, worth $200,000.
At the store the men paid a deposit of US$1000 for the ring and made arrangements to come back and pay the balance, again in two days. But they never came back and when staff reopened the box days later the ring was gone.
