A political commentator thinks the Greens are in a difficult space with regard to the Darleen Tana report. 

The embattled MP, who resigned from the party, is denying allegations of knowledge or involvement in migrant exploitation at her husband's business. 

A report into Tana has concluded but has not been made public. 

She broke her silence last night, speaking to TVNZ about her disagreement with the findings of the report. 

Former MP and commentator Peter Dunne told Mike Hosking that invoking the waka jumping legislation could mean even more weeks til the matter's resolved. 

He says its likely she's throwing down the gauntlet to the Greens.
