Finance Minister Nicola Willis says she's determined to ensure the health system is as efficient and effective as possible.

A survey by the General Practice Owners Association says 83 percent of respondents are worried about their long-term viability - with 89 percent of them planning to increase patient fees

Willis has promised the health system will look significantly different by the end of this year.

"I think it's going to be a big turnaround job.. but I think by the end of this term of Parliament, you will be seeing significant improvements."
