New Zealand's latest community case of COVID-19 was unvaccinated, due to experiencing an issue with the booking website.
The country will go into into COVID-19 alert level 4 from 11.59pm on Tuesday after the latest case in Auckland was announced just hours prior.
Director General of Health Dr Ashley Bloomfield confirmed on Tuesday evening the 58-year-old North Shore man was unvaccinated - but had been making "every attempt" to book his vaccination, as he was in the right age group to be immunised.
The man's wife was fully vaccinated and has so far tested negative. Both are self-isolating.
Prime Minister Jacinda Ardern says people who are partially vaccinated have a 30 percent reduction in their chances of infection - but regardless of vaccination status, everyone in New Zealand must comply with the rules of alert level 4.

It is unknown which strain of COVID-19 the man has contracted - but Jacinda Ardern says all decisions have been made assuming he has the highly infectious Delta variant.
New Zealand will enter COVID-19 alert level 4 from 11.59pm on Tuesday for at least three days. It's possible Auckland and the Coromandel will be in lockdown for seven days. The infected man and his wife visited the Coromandel for a weekend holiday between August 13 - August 15.
