Since its launch last week, almost all of the 10,000 copies of the Dunedin Passport has been snapped up, with a further 5000 copies to be printed, Tourism Dunedin chief executive Hamish Saxton said.
"The response has been excellent."
Residents living inside the Dunedin city boundary were eligible for the passport, he said.
People living south of the Waitaki were likely to be included in a promotion later this year aimed at encouraging more visitors into the city.
The passport offers Dunedin residents the opportunity to experience the city's tourism attractions, which would in turn make them "great hosts and ambassadors" for visitors.
With fewer numbers of New Zealanders travelling overseas, it was the perfect opportunity to boost domestic visitors and the third phase of the campaign - a country-wide marketing campaign, would begin "at a later date".
Almost 1000 passports were handed out at the Cadbury Chocolate Festival gala fun day at the Edgar Centre on Saturday, and hundreds were being given out each day to motorists leaving the Dunedin International Airport car park.
