New Zealander who may start roaming (5)
I believe the answer is:
maori
'new zealander' is the definition.
(the Maori are indigenous people of New Zealand)
'may start roaming' is the wordplay.
'start' means to remove the last letter (I've seen 'starts' mean this).
'roaming' becomes 'ori' (I can't justify this - if you can you should give a lot more credence to this answer).
'may' with its last letter removed is 'ma'.
'ma'+'ori'='MAORI'
'who' acts as a link.
Can you help me to learn more?
(Other definitions for maori that I've seen before include "Native of New Zealand and the Cook Islands" , "Pa may accommodate one" , "native person" , "Native language of NZ" , "I roam (anag)" .)
