Wanting to either find information or knowledge about whether any British Royal or Volunteer Artillery / Land Transport units or soldiers shipped out to Australia or New Zealand for military engagements. Any information would be greatly appreciated.
Note i have listings for Aus & NZ troops that fought in Crimea who did return but would like to add in the above additional info.

You will want to read the Wikipedia article on the New Zealand Wars:

https://en.wikipedia.org/wiki/New_Zealand_Wars

And this site might also prove useful.:

British Volunteer Artillery (or any volunteer, yeomanry, or militia units) were meant for home defense and not sent overseas. Some yeomanry units ended up serving during the Second Anglo-Boer War.

Is there something specific you are looking for?
