The full CPTPP text, as well as a key document outlining the impact of the trade deal on New Zealand, will be released tomorrow, all things going to plan.
The release of the full text has long been a point of contention, with opposition governments and critics across the world pointing to a lack of transparency.
Prime Minister Jacinda Ardern said she expected the full text and impact statement to be released on Wednesday.
"We've been very eager to be as transparent as possible with the final outcome of the agreement, so [I'm] pleased we will be able to share that with the public this week."
Ms Ardern said the Government made "massive gains" in areas of "natural opposition".
"I'm hoping we will be able to demystify some of the concerns that have existed and again highlight that we pushed hard and made good gains."
But the opposition is not convinced any major changes have been made.
"My analysis is there are very few changes to it. The ISDS, for instance - the New Zealand Government can still be sued. The only change is they can't be sued for contractual disagreement", National's Todd McClay said on Tuesday.
Barring any major surprised in the text, though, National will be supporting the agreement into law in New Zealand.
"Gains to New Zealand exporters far outweigh concerns people would have. I've always thought the risk of being sued is not significant," Mr McClay said.
The CPTPP text itself is unlikely to be markedly different to the former iteration of the TPP already circulating.
What's likely to be of more immediate interest to the public will be the accompanying analysis outlining anticipated effects on New Zealand.
MFAT has put together a national interest analysis, to be released tomorrow afternoon. The analysis is anticipated to include impacts on New Zealand's GDP, tariffs, growth, regulation and details on the much-criticised investor-state dispute settlement tribunals.
The impact statement is understood to include information of particular interest on the trade of beef to Japan, as well as the export of fish and seafood.
The full CPTPP text is scheduled for international release on Wednesday at 1pm, New Zealand time.
