shanreagh not really surprised that there are Khouri in NZ as the immigration records for Aus show many with that surname coming from Syria and then Labanon from the mid 1800's onwards, so some in NZ are likely related somewhere along the way. Whether or not they realte to Abraham I dont know.
The Jago(e)s are pretty interesting in their own right as they married into the Rogers family via Sinclair James, which is why the interest there. There has been a lot of them in Tasmania but where they fit I dont know at the moment.
Corbins relate to the Rogers and come from Jersey. The Corbins I know of are inVictoria and Western Australia.
