Auckland and Middlemore hospitals have only just changed from their old district health board addresses.
Health NZ / Te Whatu Ora is ditching its current Māori-language email address, even though thousands of staff have only used it for a few months.
The organisation was still switching many of its 90,000 workers to its main email domain tewhatuora.govt.nz, a process that began three years ago.
In October, they must move again to the new domain, healthnz.govt.nz.
Health NZ said the change was to emphasise its English name, but IT processes required all staff had to move to the Māori address first.
