"It's more an industry-wide problem. It was purely a cash flow thing for us. We couldn't cash flow it any further."
The business had had annual turnover of around $7.5m, one of its biggest jobs was at the airport for Fletcher Construction but it had also worked with Hawkins Construction and NZ Strong, he said.
The liquidators' report showed $650,240 is owed to Bagley & Blake for accounts receivable and retentions - amounts withheld by its clients. Bagley acknowledged this was a big issue.
"We had hoped we would recover some of those retentions," he said.
"But the bigger story here is just the problem of trying to get skills and it's right through the sector," he said, telling how paperwork on one big job was severely deficient.
He cited commercial construction working drawings "with some very fundamental flaws in them. That slows the process down."
The ongoing airport job has been estimated to be worth more than $100m and is the phase three expansion, a multi-stage redevelopment of the existing international terminal building with new outbound passenger processing areas, more duty free shops, landside and airside works and mechanical services.
The liquidators' report said Bagley & Blake was founded in 2010, specialising in full contract carpentry work, civil and concrete works.
"According to the director the reasons for the company's failure are as follows: the company cash flow was insufficient to meet day to day operation and the company was under-capitalised for rapid growth experienced in recent years," the report said.
