This section describes what money is, what cash or currency is, how New Zealand's bank notes are designed and made, and the life cycle of a typical bank note. It also looks at the design and security features of our bank notes and coins, and the history of currency in New Zealand. In ancient times, people had to barter things to trade - for instance, a cow for six pigs. This, however, was clumsy. That's where money came in.
Money is a token or measure that stores wealth.
With it, in our example above, the trade could take place. Also with money you can earn now and spend later. Early examples of money were shells and iron nails, as they could easily be counted. In due course, these were replaced by coins made of gold, silver, bronze and copper and much later paper money was developed. There's a lot more money around than just cash.
