@Nat****
you need to understand the difference between a 15 day visa-on-arrival which people from 21 countries BUY for 2000baht when they stamp into the country
AND
A 30 day visa exempt entry which people from 50+ countries get when they show up here and enter by air or land.
A New Zealand passport holder would get a 30 day visa exempt entry stamp entering by air or land BUT would be limited to TWO 30 day visa exempt entries by land in a year.
