After Hours Service

After hours service, including telephone advice, is covered by the 24 Hour Surgery (please phone 3657777). The 24 Hour Surgery is our preferred option for After Hours care, as:

  • The GPs at St Martins regularly work sessions at the 24 Hour Surgery.
  • Notes from consultations are communicated, with the patient’s consent, back to the patient’s regular GP within 1 day, thereby allowing better continuity of care.
  • Patients with complex medical problems have the facility to lodge some medical details with the 24 Hour Surgery, enabling more informed care in an emergency.
  • The Observation Unit at the 24 Hour Surgery allows patients to be observed for several hours if necessary, to enable decisions to be made on the best outcome for patients (e.g. whether hospital admission might be needed).
  • House visits are available from the 24 Hour Surgery.
  • The 24 Hour Surgery is the only facility open all night in Christchurch, every day of the year.
  • The 24 Hour Surgery is located at 401 Madras Street.


  • In case of an emergency please dial 111.
