Thailand women leaving money for Pacific kingdom (5)
I believe the answer is:
tonga
'pacific kingdom' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for tonga that I've seen before include "Horse-drawn vehicle" , "Pacific island kingdom" , "Pacific Ocean kingdom" , "South Pacific island group country" , "Polynesian Kingdom" .)
