From 2017 through 2026, New Zealand gets no significant public domain day. This is mostly because of the TPP, but not having much in the way of a rule of the shorter term is another factor.

The next New Zealand public domain day, after that gap, is January 1, 2027, then occurring annually up to, and including, 2034.

Then there is a second gap, with no public domain day in 2035 or 2036.

Significant public domain days resume on January 1, 2037 and henceforth follow Life + 70 rules.

I forgot to allow that the works falling into public domain under the life+70 rule would at first already be there under the transitional life+60 rule. So after ratification there would be a 10 year gap, then 8 years of works entering under the life+60 transition period, then another 10 years before the first new works entered under life+70.

Edit: Perhaps a simpler way to think of it is: those works that fall into public domain in the first 8 years under the life+70 rule in Canada, will fall into the New Zealand public domain 10 years earlier.

Why should any mobile reader, even in New Zealand or Vietnam, care? New Zealand's population is probably too low to support the substantial volunteer proofreading community needed to ramp up a local Project Gutenberg in 2027. As for purchased eBooks, I'd think that, in New Zealand and Vietnam, they are mostly purchased from outside vendors – think www.amazon.com.au – who are unlikely to lower a price just because the eBook is public domain in a secondary market. So, from a practical standpoint, TPP copyright leniencies granted to New Zealand, Vietnam, and Malaysia may not much matter for eBooks.

There are ebooks sold on Amazon, Kobo, etc. which are georestricted so that they only show up when buying from a country where they are in the public domain. So for example if I visit Kobo from a US IP address then I might only see the high-priced big-publisher edition, but if I visit from a New Zealand IP address then I might also see other low-priced or free editions that make use of public domain. The publisher might not bother to change their price for New Zealand, but they will surely lose sales to the public domain-based editions if they don't.
