The state-owned logging company was due to find out in February if it had achieved Forest Stewardship Council certification, and the Greens say the delay is a sign that it is facing ‘‘serious problems’’ gaining accreditation.

The auditor, SCS Global Services, conducted Forestry Tasmania’s onsite inspections in December.

Greens leader Kim Booth said Resources Minister Paul Harriss had failed to provide an update on the audit findings.

‘‘It is therefore a fair assumption that significant problems were identified during those site inspections, which have resulted in a two-month delay in determining Forestry Tasmania’s application,’’ Mr Booth said.

Mr Harriss said the government continued to support FSC certification.

‘‘We look forward with expectation to the results of the audit conducted by the independent auditors, and that should happen sometime during April,’’ Mr Harriss said.

Meanwhile, Labor has questioned whether the government will wind-up Forestry Tasmania.

Opposition Leader Bryan Green said there were no funds beyond the first year to support the company after a $30 million equity transfer from TasNetworks dried up.

‘‘All you can conclude is that there’s a black hole in the budget or Forestry Tasmania is going to be taken back into the department,’’ Mr Green said.

Mr Harriss said a review into the company was still under way, with a report due at the end of the month.

‘‘It is not appropriate to comment or speculate on what that review may or may not include,’’ Mr Harriss said.
