Willow Medical Centre is a general practice at 257 Herbert Street in Windsor, Invercargill. Its patients can have after-hours GP consultations by phone or video through its service partner, Practice Plus. That service runs from 5am to 10pm on weekdays and from 8am to 8pm on weekends and public holidays. A standard appointment covers one medical issue, and a 30-minute appointment is booked for more complex visits. The practice has a nurse prescriber who can diagnose and treat common conditions and prescribe some medicines, and who can review stable patients on simple medication. Same-day needs go through a triage list: you ask at reception to be put on it, and a doctor calls in the morning. The practice has nurse-led blood tests for a $10 fee, as at 2026, and it also offers cervical screening and iron and zoledronic acid infusions when a GP prescribes them. Free blood testing is also available through Awanui Labs, but those appointments must be booked ahead unless a doctor has marked the test urgent.
