WHAT'S really happening?

CASES

Australia Post

Australia Post engaged Warden Consulting to resolve significant unexplained losses. Traditional investigative measures had proven inadequate, prompting the need for specialised intelligence gathering and analysis. Two undercover agents from New Zealand were deployed for a year to tackle financial losses and improve operational efficiency and security within the organisation. Collaborating closely with internal investigators, their focus was on addressing drug dealing among employees. This approach led to successful identification and resolution of drug-related issues.

OPERATION HUNTER

Warden Consulting was involved in the deployment of multiple undercover agents on behalf of NZ Post in an operation coded Operation Hunter. Between September 2001 and April 2003, Warden conducted an undercover operation on behalf of NZ Post regarding systemic theft.

The operation involved the deployment of multiple agents and resulted in the recovery of property and evidence of theft amounting to approximately $1.5 million. Property stolen included passports, credit cards, mobile phones, computers, clothing, jewellery and electronic goods. Offenders included owner drivers, couriers and parcel sorters as well as former NZ Post employees. Receiving and supplying methamphetamine was also uncovered.

The termination was carried out in conjunction with approximately 80 police officers from the Auckland Police with a number of search warrants executed and in excess of 20 persons arrested and charged with a variety of offences.



FIRST EQUITY ENTERPRISES - BOILER ROOM FRAUD

This fraud investigation involved the representation of 322 clients from 30 countries in respect of the loss of USD $100 million. The funds were lost as a result of a Russian organised crime fraud operation based in New York. Warden froze funds in a BNP Paribas account in Geneva through a private Seizure Order. It was subsequently established this account contained $4.7 million and that the following day one of the offenders in the boiler room (Gary Faberov) attempted to shift these funds from the account. In the absence of the Seizure Order, Mr Faberov would have been successful. In total Warden recovered over $10 million.



SHERIDAN LESLIE COX - MENDES PRIOR FRAUD

We represented New Zealand and worldwide groups concerning the fraud offending of Sheridan Leslie Cox. Steps were taken concerning the Mendes Prior fraud operation run from Thailand and as a result, Cox was arrested on passport charges traveling into Taiwan. On a number of occasions, negotiations were undertaken with Cox whilst in custody in Taiwan with a view to recovery for New Zealand victims. Part of the recovery negotiation process involved dealing with the Minister of Justice in Taiwan. The New Zealand Government assisted this process through the Hon. Peter Dunne who attended the meeting. Further steps with other victims were undertaken in South Africa, Hong Kong, London, Singapore and Malaysia.
