The Trans-Pacific Partnership legislation has passed its first hurdle with support from National, Act, United Future - and one Labour MP.
The Trans-Pacific Partnership Agreement Amendment Bill will now be considered by the Foreign Affairs Defence and Trade Committee, after passing its first reading 62 to 59.
It was opposed by Labour, the Green Party, New Zealand First and the Maori Party. However, Labour MP Phil Goff voted for the TPP.
In January, Labour leader Andrew Little gave Mr Goff special dispensation to do so, because during Mr Goff's time as trade minister he started the negotiations for the agreement's predecessor.
Fellow Labour MP David Shearer had told the Herald he personally supported the TPP, but later said he would be voting along party lines.
