Labour leader Andrew Little has gone on the attack over mental health services on the same day an open letter calling for action was presented to Parliament.
Associate Health Minister Peter Dunne received the letter, signed by 12,800 people, from lobby group Action Station.
The letter was signed by a number of well-known New Zealanders, including film director Taika Waititi, and called on the Government to implement the four recommendations in the "People's Mental Health Report".
Released last month by Action Station, the report included the stories of 500 people, with just 7 per cent reporting positive experiences with the health system. Problems highlighted in the report include people waiting too long to access services and treatment, or being declined for treatment.
In question time, Little asked Prime Minister Bill English why funding for mental health services had risen far more slowly than demand that had seen the number of people needing services rocket by 60 per cent under National.
