"Guest nights continued to rise this month, with the South Island leading the way when compared with November 2014," business indicators manager Clara Eatherley said.
The Otago region had the largest increase in guest nights, boosted mainly by Queenstown and Wanaka.
Nights spent in the South Island rose 7 percent to 1.29 million, with international guest nights rising 8 percent and domestic nights up 5.9 percent.
Regionally, this was led by Otago - a key tourism destination including Queenstown and Wanaka - which rose 11 percent. All five regions of the South Island posted increased guest nights, with Southland rising 6.9 percent, and the West Coast 5.5 percent.
The North Island rose 2.9 percent overall. Domestic guest nights rose 4.9 percent, while international guest nights were flat. Bay of Plenty saw a 9.4 percent rise in guest nights, while Wellington and Waikato each boosted their numbers by 6.9 percent.
All four types of accommodation surveyed - hotels, motels, backpackers and holiday parks - reported gains in guest nights in November, with hotels, motels and holiday parks also showing increased occupancy rates.
