Ryurazu - no they are not. Niuean's use our currency as a unit for their garbage NCLT.
Most of it minted in USA, Germany and even China now.
Niue use our currency for everyday needs and it is all made overseas
Banknotes - Australia
$1 and $2 - UK
10c, 20c, 50c - Canada.
A few Kiwi bullion coins are made here, but we do not mint any junk NCLT coinage for anyone.
Loving Halfcrowns. British and Commonwealth coins 1750 - 1950 and anything Kiwi.
If it's round, shiny and silvery I will love it.
