New Zealand Exchange Limited (NZX) has appointed Trayport, a
leading supplier of electronic trading systems, to provide the technology for its core equity
and debt markets, following an extensive global tender process.

The new technology platform will include a trade reporting system for the electronic
communications network (ECN) being established in Australia by NZX and five major
banks. NZX announced its intention last month to establish the ECN with its banking
partners during the first half of 2007.

Under the deal, Trayport will provide NZX with its GlobalVision Exchange Trading System,
to be implemented in 2007.

“The key consideration for NZX was to build flexibility into our trading system so as to allow
us to add new products and features without the need for expensive bolt-ons. The Trayport
system will deliver flexibility and proven performance. It will enable us to support our
existing clients and markets while anticipating and responding to new market initiatives,”
said NZX Manager, Market Technologies Martyn Bain.

NZX will be working closely with NZX participants and systems providers over the coming
months to map out their exact requirements.

Edmund Hor, CEO of Trayport, said, “We are extremely pleased to announce our
partnership with NZX and to be associated with their new venture into the Australian
equities market. We believe our platform will provide NZX with the flexibility to evolve and
innovate as their business and markets develop.”

Trayport software powers 49 markets worldwide and NZX is its fifth regulated exchange
