There's concerns among experts following the latest medical platform hack that's left an impact on Kiwis.

MediMap is widely used across New Zealand, particularly in aged care, disability, hospice, and community health.

Some users' information had been changed, including altering ages, changing patient's names to Charlie Kirk - and claiming living users were deceased.

CISO Lens Country Manager Nadia Yousef says it's unclear why this happened, and there's nothing hinting towards extortion or blackmail just yet.

"It's not clear who did it, it's very unclear why - there's, I think, a lot more to follow over the next few days."
