What is the Music From the 2009 bbc2 South Pacific Documentary?

during the actual programme there is some amazing hawaiian-sounding guitar music not the "somewhere over the rainbow" isreal kam-whatever version but some really lilting strings in a regular but shifting rhythm that comes on regularly throughout the series. check out 54:49 on the 4th episode Ocean of Volcanoes its incredible any help would be greatly appreciated.

Have a look at this guy, he writes the music for that programme. theres extracts you can listen to.
