Hello maxidog
... our posts crossed - meaning I had not seen your reply before I sent my last post.
And it seems you've been able to reinstate your former registration, and get back to using your original name ?
No, a medal is not required (nor are they sought around here) ... that information was fairly freely available on a "pay site" although it may only have been a recent addition. "No" too, to being "professional" ... just returning favours. I once received wonderful help myself, from RootsChatters.

The "arrival" information I gave you
is "credible". It is an official record of the Australian Government / Immigration service, of that era.
With regard to the NZ death record - when you find it - there is no need to post a copy of the actual certificate or printout, you can just do a transcription of the information it contains.
