The liquidation of engineering group Decmil's New Zealand business has run into strife, as some of its creditors try to dump its Perth-based adviser, claiming it cannot make a seven-hour flight across Australia and the Tasman Sea during COVID-19 to assess assets.

Decmil shut down its New Zealand operations in mid-April after the country's Department of Corrections terminated a $NZ60 million ($58.3 million) prison contract due to a dispute over costs and delays. It subsequently appointed Avior Consulting to liquidate the business.
