It could become problematic if other countries like Australia start opening up and we see an exodus of young professionals including healthcare workers, the latter we're seeing severe shortages of even with no covid cases. In contrast to NZ, Australia is better resourced to live with Covid and their citizens are quite rebellious against lock-downs, so it wouldn't surprise me if they open up well before NZ which could make things very awkward if we're still fumbling around with an elimination strategy.
