What do you mean authoritative here? That the zone is not on ns1 yet?
(see below)

correct.

well, in addition to the requirement that the zone must reside on the server
to be able to AXFR from it, the server must also allow transfer from the
client you are transferring from. Check allow-transfer directive, globally
for the nameserver and locally for the configured zone. I think the default
is "none" (check the docs for sure)
