Our system has a number of challenges, and we all agree that that needs to be improved in different areas. But the workforce element within the health system is probably the most critical and fundamental aspect that is broken today. The aspects around retention of the existing staff who work within our system were pretty much forgotten in regards to the last Budget process articulated by this Government. Yet those are the very individuals across our district health boards, across our primary care sectors, across our front-line ambulance providers, across our allied health areas, across our aged-care sector that need our support. Retention is the single biggest factor—in terms of investment—that will be able to retain people within the system. Once they're gone—and New Zealand's health system leaks like a sieve to other countries, particularly Australia—it is very challenging and very expensive to get them back.
