UPDATED 11.26am: Trade Minister Tim Groser has come under renewed pressure today to release details of the Trans Pacific Partnership Agreement.

Around 20 people have turned up at Trade Minister Tim Groser's electorate office in New Lynn.

They've washing his window in a bid for greater transparency.

Organiser Lizzie Sullivan said Mr Groser needs help with transparency.

She said they are "hoping that the Government will decide to embrace democracy and release the text of the agreement."

But she said if that doesn't happen, they will converge on Wellington to get the documents themselves from the Ministry of Foreign Affairs and Trade.

Sullivan said they have issued a demand that the Government release the text of the agreement by the end of this month.

"We know that democracy can't happen behind closed doors, so we've issued a demand that the government release the text by August 31st."
