Mass migration to New Zealand or Siberia would entail would mean more construction work causing more carbon to be released.

Rather adapt existing buildings to the changing climate.

Right, but that's a global cost for a localized benefit... which is kind of the whole deal here. In any case, basically every mitigation is still going to involve massive amounts of concrete- and diesel-related emissions, whether it's new housing, flood control measures, new energy sources, carbon capture, etc etc.

Mass migration to New Zealand would pretty quickly overflow the islands.
