Does anybody know how I can obtain the SRN number I have for an ASX listed holding? Or is there a way I can sell my shares without it?

It possibly would have been sent to me in the mail, but I am overseas and my mail is on hold with NZ Post so there's no way I can get the SRN from my holding statement.

I've checked by signing into the share registry website, and that holding is unfortunately not showing in my portfolio, so I can't find my SRN there either.

I checked Sharesight and the holding is showing there but I could not find my SRN anywhere.

My holding statement with my SRN has not been sent to me electronically.

I'm running out of ideas and really want to sell these shares today, preferably as soon as the market opens. I certainly don't want to wait until I can get my mail from NZ Post.

Has anybody been in a similar situation and managed to find a solution? Surely in this digital day and age I don't need a number on a piece of paper to sell these shares.
