Ports of Auckland (POAL) has asked NZIER to estimate its economic impact. On average, POAL contributed $100 million per annum to its owners and $158 million per annum directly to the Auckland economy over the last five financial years. That Auckland is served by a port located in the centre of the city is of considerable benefit to the city and the national economy. We estimate that the location of the Port adds between $1.4 and $1.6 billion dollars to the national economy each year.
