It went into liquidation in 2012, owing $1.2 million.
Liquidator David Petterson blamed the company's failure on actions and inactions by Mr Massey and another director. He also questioned whether the council was liable for losses. Mr Massey used his council email for company business.
A High Court hearing in relation to legal action against the company, initiated by Mr Petterson, is set down for next week.
Police said this month they were investigating a fraud complaint from Mr Petterson relating to the company.
Mr Jack said the council was not involved in any proceedings relating to Nature Green.
Mr Massey declined to comment when contacted at home last night.
