In the year ending December 2017, 23,872 Indonesians visited New Zealand, an increase of 21.6 per cent on the previous year. Holiday arrivals into New Zealand for the same period increased by 28 per cent.
It's not known how many of the 23,872 Indonesians visited Northland.
Ms Chandrawinata's trip ended in Wellington.
Tourism New Zealand's Steven Dixon is confident travel packages for Indonesians would be popular after strong results from phase one of the campaign with her illustrating her value as an advocate for New Zealand.
"It has been proven to clearly communicate that New Zealand is a comfortable destination to visit and offers a wide range of activities— a great result given these are the main knowledge gaps identified among Indonesians in our latest research."
TNZ is also running a campaign to attract more Australian visitors to Northland, particularly in the off-peak season.
