>In New Zealand, the local EFTPOS network is basically a home-grown network that the major NZ banks established in the 1980s's and have continued operating on a shoe-string budget ever since. For the most part merchants only have to pay a low fixed cost to access the network, whereas customers usually don't pay a fee (as most banks either bundle free EFTPOS transactions in a fixed monthly fee package or even offer it for free entirely for certain account products).

Sounds exactly like Interac in Canada. Although nowadays I believe most if not all Interac debit cards are also co-branded as MasterCard/Visa debit. Which makes em usable online as well. (There is a Interac online but only a small small small handful of sites even support it.)
