Another mysterious aircraft has arrived in the country, as a top-secret spy conference begins.
Fairfax reported last night that a Gulfstream jet with blocked credentials landed at Wellington Airport during the evening.
A screen grab of online aircraft tracker FlightRadar24 showed the flight's arrival, but it was not known why it was in the capital.
The plane's arrival follows a cryptic week of aircraft arrivals in the country, as a Five Eyes spying network conference takes place at luxury Millbrook Resort, near the Central Otago town of Arrowtown.
