Native American shattered new pea (6)
I believe the answer is:
pawnee
'native american' is the definition.
(Pawnee is an example)
'shattered new pea' is the wordplay.
'shattered' is an anagram indicator.
'new'+'pea'='newpea'
'newpea' with letters rearranged gives 'PAWNEE'.
(Other definitions for pawnee that I've seen before include "North American Indian - one taking a pledge" , "N American native" , "one living in America" .)
