Physical distancing requirements on public transport have been relaxed following a review by the Ministry of Health to determine whether they are still required at Alert Level 2 (or below).

The Ministry's assessment is that mandatory face covering and individuals tracking their movements mean physical distancing requirements can now be relaxed.

"With the use of face coverings, our updated advice is that physical distancing should be maintained where possible, however it is not required on either domestic flights or on public transport such as trains, buses and ferries," says a statement from the ministry.

"Reports are that passengers on public transport are taking the use of face coverings seriously and regularly scanning QR codes on all forms of transport. This along with electronic ticketing on airlines means we can contract trace rapidly if required."

The advisory by Ministry of Health and Ministry of Transport for recommended seating configurations on public transport that promoted physical distancing have now been revoked, effective immediately.

People should continue to observe physical distancing where possible, says the ministry.

"Airlines and those transport operators requiring pre-bookings have been advised of these changes and can now accept higher volumes of bookings.

"If you are travelling, to work, school or on holiday, please remember to practise the core hygiene measures – disinfect hands, cough into your elbow and, most importantly, if you are unwell, please stay home."
