A former Waikato District Health Board boss labelled "arrogant" and "bombastic" has been blamed for pressuring a long-serving Australian public health servant into dishonestly hiring Stamp's daughter.
Malcolm Stamp was chief executive at Waikato DHB for 10 months before leaving early into his contract in 2007 to take up a health role in his native England.
In March last year, Queensland's Crime and Corruption Commission issued an arrest warrant for Stamp over a nepotism case involving his daughter Katy Stamp and an $80,000 salary.
Last month, Scott Andrew McMullen was handed a suspended jail term for his part in the deceit, but Stamp will only face justice if he returns to Australia, the Courier Mail reported.
McMullen had been working in public health for almost 20 years when he got a new boss at Queensland Health in 2014.
