In the two years leading up to receivership the company had substantially expanded and upgraded its fleet, Bennett said in her report.
"During the same period, it experienced some difficult trading conditions in the construction sector, including a number of substantial bad debts due to other industry failures as well as cost overruns. These issues adversely impacted its ability to meet payment obligations on a timely basis."
It's understood Tower Cranes was owed money from the collapse of Ebert Construction earlier this year.
Excluding the BNZ's claims there were 47 financing statements registered against the two Tower Cranes businesses, the receivers noted.
"We are continuing to review all registered security interests and the associated value of the goods/assets that may be held in respect to each."
To date the receivers have concluded sales of certain assets and some negotiations are continuing.
"Due to the volume of large scale assets and their specialist nature, a further realisation process is likely following completion of initial sales."
Tower Cranes' receivership is the latest in a long list of construction industry failures in recent times including:
• Mainzeal went under in 2013 with losses of more than $110m;
• Fletcher Construction is recovering after racking up losses of nearly $1b;
• Trouble arose at Alexandra Park where Canam last year left one of two big apartment blocks, replaced by CMP Construction;
• Christchurch-headquartered Corbell Construction went into liquidation in December, with $35m of projects underway;
• Arrow International went into voluntary administration in February after a contractual dispute left it with insufficient cash flow to meet operating costs;
• Fletcher's work on the $703m NZ International Convention Centre and the $1b Commercial Bay is delayed, resulting in the developers withholding millions.
• National builder Ebert Construction with creditor claims of more than $45 million but assets of only $30.1m, according to the latest report, which predicts there will be no money for unsecured trade creditors.
