[...] a way to find the names of all Births on a specific date in New Zealand?
Hello... expanding Twiggy and Spades' earlier suggestions gives a fairly straightforward way of doing what you want, namely
***searching the BDM website by date. The main problem is that it's extremely time-consuming.
Having said that, I've done it a few times. Mixed success but my latest attempt did break a thirty year old brick wall, so never say never.

What's more pertinent to your search is mentioned by Janette. Pre-1913 registering of Maori births was optional.
According to the NZ Yearbook, even in the first year of compulsory registration (1913) there were still 17 Maori births registered under the (optional) main Act from a population base of 56,000-ish Maori.
In 1900, when the population base was 43,000-ish, registering under the (optional) main Act was all that was available. The number of Maori parents who chose to register wasn't recorded but you would suspect it to be just as low as 1913 if not lower, if not zero, although I have no proof of that.
My uneducated guess is that there will be no official birth record for you to find.

For what it's worth, if you want to put up the names of the child and/or parents I can search a list of 1900 births and see if they, or variants, are mentioned.

*** Searching the BDM website by date involves a combination of searching by
"Registration Number" (e.g 1900/000001, then 1900/000002 [and so on] then 1900/29999, then 1900/30000) at the same time limiting the
"Search From" and
"Search To" to a specific date or dates (e.g Search From:2/7/1900, Search To:16/7/1900).
In this example there will be 30,000 individual search requests sent to the BDM website but the website will only return results for births which occur between the 2nd and the 16th of July 1900.
An extremely repetitive and time-consuming process but fortunately there is software which automates the search. I use the free version of UI.Vision RPA (formerly Kantu). There is also iMacros although last time I looked you needed to purchase a licence to use it fully.

EDIT: For anyone thinking the "muliple-search-request" method is abusing the BDM website... it would be incredibly easy for BDM NZ to implement a "wildcard" search option. Or a search by partial name or by date or by field. I gave up asking them several years ago.
EDIT 2: For this search to succeed the Registration Number needs to have a 1900 prefix
e.g 1900/XXXXXX
If the birth was a late registration with, for example, a 1901 prefix it would not be found... bit of a nuisance.
You could then do a 1901 births search requesting another 30,000 searches... but what if the birth was registered in 1902 ... and so on.
