Earlier this week, the company reached an agreement in principle with the government and its lenders to restructure its debts and continue operating.
Solid Energy Chairman Mark Ford said he believes the agreement will allow the company to return to profitability in the coming years and to reinvest in its mines when the market for coal improves.
"We believe the company has a good operating future," he said in a statement, "and we hope that with the continued support of our shareholder and our funders we can re-establish the company as a major employer and economic contributor in our key coal mining regions."
The center-right New Zealand government had earmarked Solid Energy for partial sale as part of a contentious asset-sales program it hopes will raise NZ$5 billion and reduce the country's need to borrow money from abroad. However, Solid Energy's financial problems have forced the government to put plans for its sale on hold.
Coal prices are likely to rise again in the longer-term. The International Energy Agency earlier this week forecast that coal would replace natural gas as the dominant fuel for power generation in Southeast Asia over the next 20 years.
