GPs say a Government funding proposal is not enough.

Health New Zealand is suggesting a 4 percent increase in GP capitation funding, the money each practice receives for each enrolled client - and letting them raise fees by just under 8 percent.

The sector's warning some practices may go under.

General Practice Chair Dr Bryan Betty says studies have shown GPs have been up to 20 percent under-funded in the past two decades.

"All this does is go some way towards cost increases over the last year - it doesn't actually fix the underlying deficit, which is getting worse."
