THE CALCULATED CONSULTANCY

Warden Consulting Limited was incorporated in 1995. Our mission was to blend investigation and law in the absence of an overarching global fraud investigation body, and to provide the world's most effective covert operations.

OUR STAKE

Warden Consulting was founded by Mark van Leewarden who established his first investigation company in 1985 while studying for his law degree. This company was eventually sold and following the management of several investigation companies, Mark went to the criminal and civil bar in Auckland. As a result of practising at the commercial bar as a Barrister, he saw the necessity for a boutique investigation company.

Both our managing director and investigations manager hold practising certificates as Barristers of the High Court of New Zealand. This makes us the only private investigation company in the world with two investigating Barristers on staff.

The company retains national investigation and security contracts with the New Zealand government and has done so for a number of years.

With expertise in fraud investigation and recovery, we have a proven track record of success: getting distribution to victims precedents in the USA and Switzerland.


Warden is also the only company in Australasia with a dedicated undercover programme, which has been operational for over 20 years.

CRIMETIME


Crimetime is the best selling book written by our company founder Mark Van Leewarden.

The blurb reads “Crimetime is the true story of a kiwi cop who survived the dangerous double life of an undercover agent and went on to become one of the world’s most successful fraud investigators. “We think you’re the type of joker who would suit working undercover. No controls, out there doing deals and drinking piss.”

And with that the young beat cop shed what was left of his uniform and slid into the underworld of strippers, junkies, crooks and gangsters. Along the way he is a key figure in a murder, weathers multiple contract hits, finds true love, gains a law degree, tangles with the russian mafia, and continues to nail the bad guys, the con artists, the career criminals, wherever he finds them.”
