Christchurch taxis have topped the list as the most expensive in the world when it comes to trips from the airport to the city, with taxis in three Australian cities named among the most expensive in the world, according to new research.
New Zealand-based Digital Hothouse did a survey of taxi fares from airports to city centres around the world for a car rental company.
The survey, conducted on June 28, included cities in Australia, New Zealand, Spain, Russia, the United States and the United Kingdom.
It found Christchurch to have the highest average taxi fare in dollars per kilometre at $A4.20/km, closely followed by Queenstown at $A4.09/km.
Wellington International Airport ($A3.50) and Auckland International Airport ($A3.46) were also in the top seven as well as airports in three Australian cities - Perth, Melbourne and Sydney.
Sydney ranked third on the list with an average taxi fare of $A3.95/km, making it the most expensive Australian airport to catch a taxi to the CBD. Sydney was followed by Perth at $A3.76/km and Melbourne at $A3.52/km.
London Heathrow Airport was the dearest outside of Australasia at $A98.19 for 29km, followed by Madrid ($A3.35/km), Moscow ($A3.23/km), Rome ($A3.03/km) and South Australia's capital Adelaide which came in at 12th spot with an average fare of $A3.03.
The cheapest airport transfer for the 17 cities included in the study was Barcelona Airport in Spain at $A2.73/km. Amsterdam ($A3.01/km), Manchester ($A2.99/km), Los Angeles ($A2.98/km) and San Francisco ($A2.90/km) also made the list of 17.
According to Digital Hothouse's research, hiring a taxi from Christchurch Airport to the city was $A42 for a 10km journey.
This was compared to $A43.95 for 16km to get from Barcelona Airport to its city centre.
Digital Hothouse's survey, done for an infographic for car rental company Go Rentals, used taxifarefinder.com to get taxi fares from airports around the world.
The company also rang taxi companies in New Zealand to ask about rates and used Google Maps to determine distances.
Blue Star Taxis Christchurch general manager Bob Wilkinson said the survey did not allow for comparisons of taxi costs on the whole because airport fees were involved.
Set costs imposed on taxi drivers at airports such as pick-up and drop-off fees varied considerably from city to city and were diluted more or less depending on the distances to the central city, Wilkinson said.
The survey was also done before Christchurch Airport dropped its pick-up and drop-off fee for taxi operators from $NZ$10 ($A9.35) to about $NZ5 ($A4.67) on July 1, so a fairer assessment of the cost for Christchurch was about NZ$40 ($A37.40), he said.
"In a lot of places in Australia the airport fees are about $2. It is certainly a lot less than we had here. We were $10. It has now dropped to $5.50," he said.
Digital Hothouse converted taxi fares into Kiwi dollars using xe.com on June 28.
It also compared its findings against the Consumer Price Index (CPI) of each country, which showed Americans travelling from McCarran International Airport in Las Vegas to the city were really getting the shortest straw.
In Las Vegas, the cost per kilometre was $NZ3.68 ($A3.44) - about $NZ1 less than in Christchurch.
However, when compared to the country's CPI, it was the most expensive taxi trip from the airport to the city in the world.
Christchurch ranked 3rd, Queenstown 4th, and Wellington and Auckland were 6th and 7th.
The taxifarefinder.com website says fares can vary depending on unforeseen factors, such as bad weather, unusual traffic congestion and individuals' driving habits.
"However, under normal driving conditions, our fares are known to be very accurate."
