The Health New Zealand leader says their cost growth has plateaued.
Its report for the June quarter shows the preliminary result for the financial year is a $934 million deficit.
Earlier, in quarter three, a $299 million surplus was forecast.
Chief Executive Margie Apa told Heather du Plessis-Allan they've stopped their cost growth and have stabilised in the past quarter.
She says they need to take out costs and balance that with delivering on targets, using the core workforce they have.
