He says the days the case visited – 22-23 November – were "pretty quiet" with no conferences held.
"There's been no information as to what [the person] was doing."
The ministry assured that there is no new Covid-19 cases in the capital, but urged anyone who was at the hotel between 8am Monday November 22 and 7.30am Tuesday 23 to self-monitor for Covid-19 symptoms for 10 days.
If symptoms develop, they must get a test and isolate either until a negative result is received, or for 24 hours after symptoms have resolved.
A ministry spokesperson told the Herald inquiries into the case and any more potential locations of interest were still ongoing.
Covid-19 has spread into the South Island with three new cases recorded in Nelson-Tasman district yesterday.
"All three cases are in isolation, with investigations into the source of infection ongoing," the ministry said.
"So far, initial case interviews have identified a small number of close contacts, who are also isolating with testing arranged."
