A sales pitch for the benefits of the TPP is also likely to be made.
Trade Minister Todd McClay will table the national interest analysis (NIA) of the agreement, which has already been publicly released.

Parliament's foreign affairs and defence committee will then consider the NIA and hear submissions on it anti-TPP activists have urged opponents to both submit and, if possible, attend any committee hearings.
Labour leader Andrew Little said the Prime Minister could talk all he wanted about the TPP, but the truth was that independent analysis had shown the economic benefits would be slim, for the high price of an erosion of democratic rights.
Mr Little said he would today also make the point that the Government does not stand up for New Zealanders, nor have any plan for a strong economy.
The world economy was facing headwinds, but there were longer-term challenges including how the nature of work would change.
"You would think that a government after seven years in office would have taken real steps to achieve diversification, which they just haven't done."
NZ First leader Winston Peters said his party would be focused on the economy, championing changes more meaningful than those to be made to the Resource Management Act, and protesting "the path to separatism" that the Government was taking the country down.
