Abstract
Background
Cervical cancer is caused by high-risk types of human papillomavirus (HPV). Testing for
high-risk HPV is a more sensitive screening method than cervical cytology for detecting cervical changes that may lead to cancer. Consistent with recent evidence of efficacy and
acceptability, Aotearoa New Zealand plans to introduce HPV testing as the primary
approach to screening, replacing cervical cytology, from mid-2023. Any equitable cervical
screening programme must be effective across a diverse population, including women that
the current programme fails to reach, particularly Māori and those in rural areas. Currently,
we do not know the best model for implementing an equitable HPV self-testing screening
programme.
Methods
This implementation trial aims to assess whether a universal offer of HPV self-testing
(offered to all people eligible for cervical screening) achieves non-inferior screening coverage (equal) to a universal offer of cervical cytology alone (the present programme). The
study population is all people aged from 24.5 to 70 years due for cervical screening in a 12month period (including those whose screening is overdue or who have never had screening). A range of quantitative and qualitative secondary outcomes will be explored, including
barriers and facilitators across screening and diagnostic pathways. This study takes place in
Te Tai Tokerau/Northland which covers a diverse range of urban and rural areas and has a
large Indigenous Māori population. A total of fourteen practices will be involved. Seven

Te Ara Waiora – Implementing HPV self-testing in Aotearoa New Zealand
Funding: This project received funding from The
Health Research Council of New Zealand: Health
Delivery Research Project Grant 20/960, The
Ministry of Health – Manatū Hauora, New Zealand,
and Mahitahi Hauora Primary Health Entity. The
study sponsor (Victoria University of Wellington),
the Health Research Council of New Zealand, and
the Ministry of Health – Manatū Hauora, have no
role in study design; collection, management,
analysis, and interpretation of data; writing of the
report; and the decision to submit the report for
publication. Mahitahi Hauora fund a proportion of
the laboratory tests. Two co-investigators from
Mahitahi Hauora (M-AC and GJ) contributed to
adapting the study database canSCREEN® and
operational management of the study and will
contribute to writing of the report. Neither the study
sponsor nor any of the funders have ultimate
authority over any of the above-mentioned
activities.
practices will offer HPV self-testing universally to approximately 2800 women and will be
compared to seven practices providing routine clinical care (offer of cervical cytology) to an
approximately equal number of women.
Competing interests: Co-investigators are
clinicians with clinical responsibility for
participants. This is acknowledged by the research
team as potential for conflict of interest. However,
the dual role of clinician being also researcher in
this study would appear to be appropriate as the
participant will have her usual clinician providing
care, advice and follow up. This will be fully
disclosed and discussed with the participants. Coinvestigators are not remunerated for recruiting
participants to the study.

Discussion
This trial will answer important questions about how to implement an equitable, high-quality,
effective national programme offering HPV self-testing as the primary screening method for
cervical cancer prevention.

Background and rationale
Cervical cancer is now preventable by vaccination and screening [1]. Screening can detect precancerous lesions that can be treated, thereby preventing the development of potentially fatal
disease. Cervical cancer is caused by high-risk types of human papillomavirus (HPV). It is
globally recognised that testing for high-risk HPV is (...truncated)
