Funding for UK PhD students studying overseas


I am in New Zealand doing my PhD and my funding runs out (aggh!) at the end of October. I am currently trying to work out how I will support myself as I finish off the write up. I've one option that is NZ based but am also trying to look into the option of UK funding sources. Does anyone know of any funding available for students from the UK doing PhD study at an overseas institution? been doing lots of googling but all that comes up is funding for UK students studying at UK institutions wanting to go overseas to study short term, or students from overseas wanting to study in the UK. I found this but still not having any luck finding anything. Maybe it just doesn't exist.

If anyone here knows of anything that might be an option for me I'd really appreciate a heads up. I'm looking to apply for about 5k, and I'm in Social Sciences.

Thanks :-)
