so it means that people still can apply through SMC off-shore without job offer and can get approved without any conditions?
Yes.
The NZ government does not supervise what happens after the grant of visas. The cost and trouble would be entirely prohibitive, and the NZ public would not approve of the resulting intrusion into personal lives - those of employers, as well as of the incoming workers. Those granted a Residence visa without a job offer have been judged to have a good chance of finding a way to settle into NZ life. It's up to them how they do it, just as it would be if they were between jobs in their country of origin. (They won't be eligible for benefits in NZ for two years after their arrival, so there's nothing there to tempt them.)
As with many aspects of the immigration process, we have to go with what NZ law actually IS, rather than our opinion on what might be better in some way.
