Biden made an oblique reference, saying that "together, we have led the way in creating high-standard trading agreements that are necessary to uphold the liberal economic order of this new century; agreements that protect workers' rights, preserve the environment, and significantly safeguard intellectual property". But this means nothing without ratification.
Obama's only option is to try to get TPP over the congressional line during the lame duck session following the presidential election, irrespective of the election campaign dynamics.
Biden's comments in both Australia and NZ suggest the odds of getting it passed are not high. But it is important that the Administration gives TPP a solid go.
TPP should have been high up the list for questions at the joint press conference held by Biden and the Prime Minister. The Vice-President's advance team ruled that out.
A well-placed NZ source suggested the US wanted to "derisk" any possibility that he might say something that would cause either a stir here or - perhaps more importantly - a ruckus back home, where the Republicans were getting poised to anoint the blatantly xenophobic Donald Trump as their presidential candidate.
There shouldn't have been any concern. Biden did relent and allowed a question on TPP.
His response: "I think in the lame duck session we have a real chance for that happening. The lame duck means after this general election takes place in November and before the Congress adjourns. I'm hopeful."
In Australia, which has a much stronger and enduring relationship with the US, Biden said TPP would struggle to get over the line. "Xenophobic" language during the presidential campaign had had an effect.
"It's going to be hard to pass in both our countries, maybe not as hard for you [Australia], we're going to try to do a lame duck session in the US congress," he told an Australian business gathering.
Biden noted "the nature of the debate in the campaign that is playing on fear and not on hope".
"Who knows what it is going to take."
The readout from the NZ Cabinet is more layered. "Everyone can see there are potential risks," was Key's response.
"He [Biden] believes it can be ratified during that period between November and January."
Trade Minister Todd McClay suggests that while Trump and the Democratic presumptive nominee Hillary Clinton oppose TPP in its current form, the US Trade Representative will produce a strategy to move forward. Being bullish in public is not part of that.
The visit's dominant issue was the largely symbolic return of US warship visits after the lengthy Anzus impasse.
This is yesteryear's issue. The struggle for regional supremacy between the two Asia-Pacific heavyweights - the US and China - is much more important.
But even more so is delivering on a deal which has been signed but not ratified.
