Where
The corridors
The United Kingdom, Ireland and Sweden all sit in the clean antipodal band, where a Fellow's daytime covers the home night in full. Each corridor has been worked through in both directions: their radiologist hosted in New Zealand, and a New Zealand radiologist hosted there.
The twelve-hour offset matters most for on-call cover. Other offsets still work for other kinds of contribution: a Fellow at a partial offset can work in a subspecialty team, attend home MDMs and teaching, and typically still cover some evening and overnight work. What needs to be explicit is which portion of the clock each corridor covers, rather than whether it qualifies.
At a glance
 United Kingdom |  Ireland |  Sweden | |
|---|---|---|---|
| NZ radiologist there | Up to 12 months on the academic visitor route | Up to 12 months on the visiting academic permission | Up to 6 months, treated as the ceiling for now |
| Beyond the ceiling | Move to another corridor, or the Youth Mobility Scheme (under 35) or Ancestry visa | Move to another corridor, or citizenship by descent, or the income-based Stamp 0 | Outside the current scope; requires separate structuring |
| Their radiologist in NZ | Up to about 9 months on a visitor visa or NZeTA, remote work permitted, no New Zealand registration required — common to all three corridors (see below) | ||
| Registration question | Untested; confirm with the GMC and CQC | Untested; confirm with the Irish Medical Council | Untested; confirm with the National Board of Health and Welfare |
| Employer cost there | PAYE from day one, plus National Insurance; no social-security agreement | PAYE and PRSI; no social-security agreement | Social security only, about 19% at the foreign-employer rate, with provision to transfer the obligation to the radiologist |
| Data | New Zealand holds UK data adequacy; transfer is straightforward | Free movement under EU adequacy | Free movement under EU adequacy |
| Time shift | Clean antipodal: the working day covers the home night in full | Clean antipodal | Clean antipodal |
United KingdomBoth directions workable. The academic visitor route carries the outbound direction to twelve months; the open questions are GMC/CQC confirmation and the employer payroll position.
UK corridor
IrelandThe visiting academic permission processes quicker and lighter than the UK equivalent, and EU adequacy keeps data simple in both directions. Citizenship by descent opens longer stays for some.
Ireland corridor
SwedenClean up to six months, with a favourable tax position under the 183-day mark, and a natural first leg before a UK or Ireland placement: the Schengen travel allowance survives it intact.
Sweden corridor
The New Zealand side, common to every corridor
New Zealand's 2025 remote-work change is a real enabler for inbound Fellows, though it is not a bespoke visa. From 27 January 2025 every visitor visa and NZeTA permits unlimited remote work for an overseas employer; the UK, Ireland and Sweden are all visa-waiver nationalities. A single-entry visitor visa caps a stay at about nine months in any eighteen-month period, which covers the shorter Fellowship tiers; longer inbound placements need a different visa class.
The obstacle most people assume exists, New Zealand medical registration, does not in fact arise. The Medical Council of New Zealand does not require its registration for a doctor who is physically in New Zealand but reports only patients located in another country (Statement on Telehealth 2020, clause 18). The trigger is the patient's location. Because a Fellow reads only home-country patients, they sit inside the carve-out. The position is regulator guidance rather than statute, so it is being re-confirmed rather than assumed, and an absolute firewall between the Fellow and New Zealand patients is maintained.
From 1 April 2026 a non-resident visitor tax category allows a qualifying visitor up to 275 days in any eighteen-month period without becoming a New Zealand tax resident, exempts their overseas employment income, and disregards their presence when testing whether their overseas employer has a New Zealand permanent establishment. The remaining per-person item is indemnity: each Fellow obtains written confirmation that cover extends to reporting performed while resident in New Zealand.
Two questions recur in every corridor
Neither is resolved by a visa, and both are the principal reason the feasibility work exists.
The reverse of the New Zealand direction is also structurally harder: none of the three partner countries has a route designed for salaried clinical staff on multi-month remote placements, which is why each corridor leans on its academic or hosted routes, and why longer time abroad is built as a circuit across corridors rather than a single long posting.
