Auckland-based health IT services provider Whānau Tahi has bought fellow Auckland firm SimplHealth, best known for developing the New Zealand ePrescription Service (NZePS) that is currently being rolled out as well as for its role in designing Australia's eRx prescription exchange.

Whānau Tahi, which bought shared care planning software specialist HSAGlobal and its Connected Care Management Solution (CCMS) last year, is the IT services arm of the Waipareira Trust urban Maori authority.
