There's fears of potential flow-on effects from more cost-cutting at Health New Zealand.

The Public Service Association says the health agency is cutting a net 1478 roles, with about 700 already vacant.

Health NZ says it's spending more than it has in its budget - and these savings will strengthen its front-line.

PSA health sector lead, Ashok Shankar, says these cuts will impact Health New Zealand's digital team.

He explained not having these workers could lead to more outages and less data and information.
