NZDs is available on New Zealand's well established exchange, dassetX.com. This is where the peg (NZD:NZDs) is maintained. Users can sign up easily to begin on/off ramps to fiat currencies (NZD, USD, EURO). NZDs will have access to South American fiat via a market maker and a number of exchanges.
Further exchanges will be added to provide for Asia Pacific fiat on/off ramps over the next couple of months.
