ASX-listed e-health vendor IBA Health has secured AU$3.5 million worth of contract extensions with three New Zealand district health boards through its subsidiary iSOFT.

Waikato, Lakes and Tairawhiti District Health Boards (DHB) have separately signed deals to extend contracts with the e-health vendor for its i.Patient Manager and HealthViews software, according to a statement to the ASX today.

Waikato's three-year extension covers its use of i.Patient Manager software, installed at several of the district's hospitals in April 2007. The deal was signed following iSoft's agreement to add functionality to the current system, according to IBA Health.

Meanwhile, Lakes and Tairawhiti DHBs have signed five-year deals following joint reviews of existing iSoft systems at the boards' hospitals. Waikato's implementation will be a template for future system improvements at Lakes' and Tairawhiti's hospitals.

"The solid relationship with Waikato, Lakes and Tairawhiti, gives all parties the certainty and confidence to agree to long-term commitments and us the ability to offer favourable commercial terms," Gary Cohen, IBA Health's CEO and chairman said in a statement.
