The Taranaki District Health Board wants its pulse oximeters back.
Hundreds are in circulation with people who've now recovered from Covid-19.
They don't come cheap - at about $90 each - and they're needed for new patients.
It's not the only the DHB wanting them back.
Last month the MidCentral DHB offered $20 grocery vouchers for the return of its pulse oximeters.
Taranaki District Health Board chief operating manager Gillian Campbell spoke to Susie Ferguson.
