Family doctors in Christchurch say free urgent medical treatment will be extended for those most in need of it.
Pegasus Health has outlined measures it says will ensure all practices in the quake-hit city are still open and viable businesses when people return.
Free urgent medical treatment was to finish this Sunday.
Pegasus also says people who have moved to other parts of Canterbury may pay local GP charges rather than a casual fee.
It will also provide financial support for up to 30 practices in the hard-hit eastern part of the city.
Pegasus says GPs in the east are half as busy as normal but those in Kaikoura, Rangiora and Kaiapoi are flat out.
