Good luck Aucklanders

any chance of a link to that please?

so far i've only seen them state no link to strains in the first outbreak (ie first lockdown). no mention of no link to returnees that i've seen.

Ultimate source is the the Director general of health via recent press conferences, but hear is a link anyway:

https://abcnews.go.com/Health/wireStory/puzzling-zealand-virus-outbreak-grows-17-cases-72343407

Don't read too much into it it has not been possible to analysis the virus genome from all confirmed cases at the border.

Also there are ways that the virus could leak through the border without going via isolation facilities (such as via the isolation exemptions (NZ based air crew, diplomats, Marine crew, or via forigen based air crew that are required to isolate in a hotel (not managed?), but I don't think are required to be tested.)

Night before last on newshub. You'll find it if you look, I can't be bothered.

Here ya go, only took a few seconds so. ,

See relevant sentence: However, at this stage the scientists from ESR and the University of Otago have not been able to link these new B.1.1.1 cases to any that have been in managed isolation - but they still have some sequencing to do.
