ACC said, in its just-released annual report, that “lower-than-expected rehabilitation performance” contributed towards it reporting a wider-than-expected $7.2 billion deficit in the year to June.

In the previous year, it reported a $911 million surplus.

NZ Herald Wellington business editor Jenee Tibshraeny unpacked the factors behind the deficit - and examined how the insurer could turn things around.
