Auckland Airport has had some of its data delayed because of ongoing difficulties being experienced by Statistics New Zealand following the recent 7.8-magnitude earthquake centred on Kaikoura.
Wellington felt the effect of the earthquake and some buildings are still closed or awaiting demolition.
The airport company reported its international passenger numbers increased by 10.8% in October to 796,124, compared to the previous corresponding period.
However, the company said its top 10 arrivals by country of last residence data was unavailable this month due to Statistics NZ delaying the publication of its monthly international travel and migration data.
On its website, Statistics NZ said it was not yet able to load detailed migration and data travel to ''infoshare tables'' because it could not yet access required computer systems.
The department would advise users when the data was available, once those systems were restored.
The overseas merchandise trade figures would be released on schedule tomorrow. However, international visitor numbers, linked employer-employee data and household expenditure figures would not be released this week.
Auckland Airport said it achieved strong growth across all regions. Asia/Middle East international passenger numbers were up 19.3%, the Americas were up 33.7%, Tasman up 4.9% and the Pacific routes were up 6%. The growth was driven by the double digit increases in airline seat capacity.
The airport's domestic passengers increased by 12.7% to 730,965 in the month. Domestic passenger growth was driven by increased capacity on main trunk and regional services from both Air New Zealand and Jetstar, as well as a 3.4% improvement in total domestic load factors compared to last year.
Queenstown Airport had 27.5% growth in international passenger numbers. Growth was driven by additional shoulder season capacity on international routes. The Melbourne and Sydney routes were both up 32% on October last year.
