Tonight, those at the bottom of the South Island will be first to see the station, as it will come in from the south-west and head in a north-east direction across the country.
Magnani revealed the best times for select areas in the South Island to view the space station on Twitter.
The ISS will be visible in Otago skies from approximately 7.27pm, moving to Canterbury at 7.28pm and onwards to Wellington at 7.29.
