Dr Kelsey said the stance of economists and politicians supporting the deal - that, even if the trade deal does not lead to billions of dollars flowing into New Zealand, it's better to be at the table now than miss out on future opportunities - "is a continuation of the 'there is no alternative' trade deal arguments that accompanied the neoliberal era".
"That era brought us increased inequality and child poverty, especially among Maori, and is unsustainable. We need to help construct a different table."
Dr Kelsey said the TPP could weaken existing partnerships within the Treaty and could also enable international interests to undermine the Treaty.
Dr Kelsey said the TPP will do little to narrow the gap between thriving and struggling regions within New Zealand.
"Local and regional government is covered by the agreement, and the ability to take steps to promote the regions is constrained by the TPP."
