Despite restructuring and recent improvements to gross margin and market share, he said the company continued to make ongoing trading losses.
Retail workers' representative First Union, which has only one Postie Plus member in Northland, said the best hope for affected workers was if the business was sold as a going concern rather than ending up in either receivership or liquidation.
"We [union] weren't surprised because the business has really struggled in the last two years," union retail secretary Maxine Gay said.
She said one of the problems that resulted in voluntary administrators moving in was Postie Plus' dispute with its distribution and logistics' provider Kuehne+Nagel International that led to both parting ways recently. Postie Plus' financial woes meant the company was required to report to its bank on a week-by-week basis, she said.
"The appointment of voluntary administrators means creditors are held at bay a little and they've told us that they've received interest from buyers ... although, under our collective agreement there's provision for redundancy, they are very modest."
