No TV briefing today so info was from MOH website individual case data. Also checked Stuff but a bit too soon it appears (live update link just said 3 new cases, no details).
Source identified for only one case in the MOH data; ie. under 'Overseas travel', one case = no, the other two blank.
It's not the easiest to find on the MOH website, but the current press releases is at https://www.health.govt.nz/news-media/media-releases/3-new-cases-covid-19-3
