Other target results showed WDHB to be second in the country for increased immunisation with 96 per cent, against the target of 95 per cent.
Whanganui Regional Health Network chief executive Judith MacDonald thanked her staff for their effort in achieving the target.
"We know Wanganui's primary health staff are doing everything they can to make sure children in our community are immunised and immunised on time, and it's not easy when families move around or children become sick, but our staff are tenacious and it's paid off," she said.
While Mrs MacDonald was hoping primary health workers would reach the 90 per cent target for better help for smokers to quit, she was heartened that the result had moved to 87 per cent from 84 per cent in the previous quarter.
WDHB achieved 96 per cent for the 95 per cent set for hospitals.
While it surpassed five of the six health targets, it was lagging more than 20 per cent behind the 85 per cent target for providing faster cancer treatment, at 62 per cent.
Mrs Patterson said she was comfortable that WDHB staff had good systems in place to help them lift the results. The target asks that 85 per cent of patients will receive their first cancer treatment or other management within 62 days of being referred. The target will increase to 90 per cent by June 2017.
