Asian rarely seen collecting post (8)
I believe the answer is:
nepalese
'asian' is the definition.
(Nepalese is an example)
'rarely seen collecting post' is the wordplay.
'rarely' is an anagram indicator (rare can mean unusual or strange).
'collecting' means one lot of letters goes inside another.
'post' becomes 'pale' (I've seen this before).
'seen' anagrammed gives 'nese'.
'nese' enclosing 'pale' is 'NEPALESE'.
(Other definitions for nepalese that I've seen before include "Gurkhas" , "from Asia" , "foreign" , "Asians" , "High Country people" .)
