New Zealand Antimicrobial Stewardship & Infection Pharmacist Expert Group (NAMSIPEG)


Antimicrobial resistance (AMR) is a global crisis, slower burning than COVID-19 but potentially as catastrophic. It is a growing problem in Aotearoa New Zealand and may cost us dearly – longer hospital stays, poorer outcomes from interventions like surgery and cancer-related care, increased mortality, and elevated healthcare costs.

The New Zealand Antimicrobial Stewardship/Infection Pharmacist Expert Group (NAMSIPEG) aims to progress antimicrobial stewardship (AMS) in Aotearoa New Zealand. The group is mainly made up of hospital-based pharmacists who specialise in AMS/infection and is strengthened by collaboration with both NZHPA and PSNZ.


Over its first two years, NAMSIPEG have been involved in a range of activities:

  • Continues to advocate for antimicrobial stewardship nationally and to support consistent best practice via engagement with relevant stakeholders including Manatu Hauora - Ministry of Health, Te Whatu Ora - Health New Zealand, Pharmac, Health Quality Safety Commission, He Ako Hiringa, NZ Formulary, NZHPA Notes on Injectable Drugs, ESR.
  • Members (or have recently been involved in) various national groups including the:

       - Health Antimicrobial Resistance (AMR) Coordination Group (MOH)

       - Chief Science Advisor to the Prime Minister Expert Panel for 2022 report - Kotahitanga: Uniting Aotearoa against                infectious disease and antimicrobial resistance

       - COVID-19 Therapeutic TAG (MOH and Pharmac)

       - Anti-Infective subcommittee (Pharmac)

       - Infection Prevention Advisory Group (ACC)

      - National Infection Prevention and Control Expert Group (MOH)

      - Collaborations with ASID-NZ and Sepsis Trust

    Future directions

    Over the next couple of years we hope to land WAAW initiatives that are meaningful for the Aotearoa NZ context, including a focus on equity and on blending antimicrobial stewardship into sepsis management.
