The auditor's resignation comes a week after managing director John Duncan expectedly stepped down after joining Pyne Gould in 2009 from a 15-year career with Macquarie Group.
Businessman George Kerr replaced Duncan with immediate effect, having taken control of Pyne Gould via his Australasian Equity Partners No 1 LP (AEP) venture with US hedge fund Baker Street Capital.
AEP secured 76 per cent of the company in a 37-cents-a-share takeover bid that closed in March.
Kerr became involved in Pyne Gould in 2009, taking a cornerstone stake after the company faced large writedowns on the value of its Marac finance unit's property loan book, which has since been divested.
Since his involvement, Pyne Gould has taken stakes in the Kerr-managed Torchlight funds, which specialise in squeezing value out of distressed assets, and its board approved increasing the capital available to Torchlight to "seek modest investments beyond the Torchlight fund."
That includes a $7.5 million stake in an overseas equities fund, the management contract of ASX-listed IEF Real Estate Entertainment Group, and essentially seized control of the ASX-listed RCL Group, which invests in residential properties across Australia and in Queenstown, by buying up its debt facilities.
Pyne Gould's shares fell 5.9 per cent to 32 cents yesterday, and are 14 per cent below AEP's takeover offer.
