I understand, that they would like to have a closer look at the actual document (I send a validated copy with the marking sheet), since not every university teaches research to the same extend = has the same standards; however, the British system is very similar to the NZ one, so you might get away with just the abstract - if you want to risk itdo you send the entire copy or just part of it
My application guideline document doesn't state this (it is very old and short, though); I wouldn't worry too much, if it is to validate your work, send in whatever you have got; make sure, you send one for every clinical area, and maybe at least one recent onetime frame
