Not sure. But if thou gets it notarized, I have seen a statement one can add that says using the notary does not change jurisdiction. See full declaration here.

Use of a Notary is for attestation and verification purposes only and does not constitute a change in status or entrance into or acceptance of foreign jurisdiction.

Also, might be better to create a trust and put everything in the trust, then it's possible that nothing needs to be probated. And if there is no probate, then maybe no will is needed. But make sure the living man creates the trust, not the person. 

Just my two cents. Not sure if the above will help. 

Side question: does thou use "me" instead of "i" when speaking? Some people avoid use of "I" since it can be heard as "Aye", meaning "yes".

I don't think the legal fiction nz govt corporation has any jurisdiction over the will of a flesh-blood man. One must declare oneself to be a man and acting as a man, not through a commercial corporation. Then one must direct a will executor to execute the will directions when thy dies. Thou must educate the executor. 

I think a private trust would also help. As far as I know, a will is only needed in probate, and if everything is in a trust, there is nothing to probate. The trust must be created by the man, not the person.
