Maori perhaps painted on a bust (10)
I believe the answer is:
antipodean
'maori perhaps' is the definition.
'painted on a bust' is the wordplay.
'bust' indicates anagramming the letters.
'painted'+'on'+'a'='paintedona'
'paintedona' with letters rearranged gives 'ANTIPODEAN'.
(Other definitions for antipodean that I've seen before include "extreme point" , "from NZ?" , "coming from Perth" , "From Australia and New Zealand" , "as far away as possible" .)
