New Zealander almost turning up for ramble (4)
I believe the answer is:
roam
'for ramble' is the definition.
(synonyms)
'new zealander almost turning up' is the wordplay.
'new zealander' becomes 'Maori' (the Maori are indigenous people of New Zealand).
'almost' means to remove the last letter (almost the whole word is kept).
'turning up' says the letters should be written backwards.
'maori' with its final letter removed is 'maor'.
'maor' in reverse letter order is 'ROAM'.
(Other definitions for roam that I've seen before include "Travel widely" , "Peregrinate" , "Rove or ramble" , "Travel aimlessly" , "Prowl" .)
