Sounds quite serious:
Of those leaving the country on a long-term basis, an estimated 81,200 were New Zealand citizens – a 41% increase on the previous year. The figure is a rise from the previous record of 72,400 departures in 2012.
With 24,800 New Zealand citizens arriving during the period, that put the net migration loss of citizens at 56,500 – exceeding the previous record of 44,400 in 2012.
They really do mean "record". I think if we adjust it for population growth since 2012, it's not as stark but it's still bad.
