May i know what is 189?

I know this is australian migration we are talking, but is it possible to get a working visa without any employment offer?

Heavily consider to migrate to new zealand and i'm in their List of skilled occupation and long term skilled shortage

Sent few CV to secure a job 1st, even stated i'll pay for my own visa

Wife is an MO in govt hosp, so i guess we both lil bit qualify to secure a visa

Any advice?
