Methods: This study analysed the demographic data for PV, ET and PMF collected by the New Zealand Cancer Registry (NZCR) between 2010 and 2017. Results: We found that the NZCR capture rates were lower than average international incidence rates for PV and ET, but higher for PMF (0.76, 0.99 and 0.82 per 100,000, respectively). PV patients were older and had worse outcomes than expected, which suggests these patients were reported to the registry at an advanced stage of their disease. Polynesian patients with all MPN subtypes, PV, ET and PMF, were younger than their European counterparts both at the time of diagnosis and death (p &lt; 0.001). Male gender was an independent risk factor for mortality from PV and PMF (hazard ratios (HR) of 1.43 and 1.81, respectively; p &lt; 0.05), and M\u0101ori ethnicity was an independent risk factor for mortality from PMF (HR: 2.94; p = 0.006). Conclusions: New Zealand Polynesian patients may have increased genetic predisposition to MPN, thus we advocate for modern genetic testing in this ethnic group to identify the cause. Further work is also required to identify modifiable risk factors for mortality in MPN, in particular those associated with male gender and M\u0101ori ethnicity; the results may benefit all patients with MPN.<\/jats:p>","DOI":"10.3390\/curroncol28020146","type":"journal-article","created":{"date-parts":[[2021,4,18]],"date-time":"2021-04-18T22:15:13Z","timestamp":1618784113000},"page":"1544-1557","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["The Epidemiology of Myeloproliferative Neoplasms in New Zealand between 2010 and 2017: Insights from the New Zealand Cancer Registry"],"prefix":"10.3390","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7369-8639","authenticated-orcid":false,"given":"Chris","family":"Varghese","sequence":"first","affiliation":[{"name":"Blood and Cancer Biology Laboratory, Department of Molecular Medicine &amp; Pathology, School of Medical Sciences, The University of Auckland, Auckland 1023, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tracey","family":"Immanuel","sequence":"additional","affiliation":[{"name":"Blood and Cancer Biology Laboratory, Department of Molecular Medicine &amp; Pathology, School of Medical Sciences, The University of Auckland, Auckland 1023, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Ruskova","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Auckland City Hospital, Auckland 1023, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edward","family":"Theakston","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, Auckland City Hospital, Auckland 1023, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8378-8048","authenticated-orcid":false,"given":"Maggie L.","family":"Kalev-Zylinska","sequence":"additional","affiliation":[{"name":"Blood and Cancer Biology Laboratory, Department of Molecular Medicine &amp; Pathology, School of Medical Sciences, The University of Auckland, Auckland 1023, New Zealand"},{"name":"Department of Pathology and Laboratory Medicine, Auckland City Hospital, Auckland 1023, New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1599","DOI":"10.1002\/ajh.26008","article-title":"Polycythemia vera and essential thrombocythemia: 2021 update on diagnosis, risk-stratification and management","volume":"95","author":"Tefferi","year":"2020","journal-title":"Am.
