Auckland International Airport Ltd has tripled its profit due a jump in the number of people flying, and higher retail and carparking income.
The company made $100.7 million in the year to the end of June, compared with $29.6 million the previous year.
Excluding one-off charges and revaluations of assets, the airport's underlying profit rose 15% to $120.9 million.
Growth in passenger numbers was due to more people travelling internationally. Domestic patronage remained flat.
AIA also has stakes in Queenstown airport and two airports in Queensland, which all experienced a rise in passenger numbers.
