Fun things to do under $20 in New Zealand

"Imagine immersed in ancient hot water in the middle of a rain forest next to a forest stream. All this absolute bliss for $12 adults and $6 for kids. And if you want to swim head to the lower and much larger pool."

"It might be a tad over $20 at $28 for adults who want to swim but seniors can go for $5 so grab grannie and grandad or maybe mum and dad will just watch at $5. Guaranteed to be the best day forever. Opening in November for the season."
