Hi Olwen,
I hope your next Dr. will give you better options for treatment. If not, I would be on the phone to Bristol Myers Squibb, and to Merck. They are the manufacturers of the newest immunotherapy drugs.(Opdivo and Keytruda) I dont know how it works in New Zealand, but there are many cases when the drug company will allow you to have the drug under a "compassionate care" scenario. You may need to get your oncologist to speak to them as well regarding this......so even though it has not been officially approved for head/neck cancer, it seems that it can be prescribed off-label, at least it is being done so here in U.S. So keep that in mind.....hoping for the very best for you and your partner.
