The PM on Breakfast TV has just said that she wants more powers for the Immigration Service, to stop a repeat of the Iraqi officials fiasco, so they can do more investigations.
This seems to miss the point entirely. The diplomat actually wrote on his form his former role, and NZIS just did nothing with it. No amount of extra powers would fix that. It is the incompetence of NZIS that is the issue.
Personally I’d be nervous about giving an incompetent department even more powers.
