Chairman got religious instruction from a New Zealander (5)
I believe the answer is:
maori
'a new zealander' is the definition.
(the Maori are indigenous people of New Zealand)
'chairman got religious instruction' is the wordplay.
'chairman' becomes 'Mao' (Chinese leader Chairman Mao).
'got' says to put letters next to each other.
'religious instruction' becomes 'RI' (abbreviation).
'mao'+'ri'='MAORI'
'from' is the link.
(Other definitions for maori that I've seen before include "Native of New Zealand and the Cook Islands" , "I roam (anag)" , "aboriginal inhabitant" , "Native Kiwi" , "Aborigine of New Zealand" .)
