Transport costs for households jumped $2 billion within one year, according to Statistics New Zealand.
Between 2016 and 2017, the average amount New Zealand households spent on transport rose from $18b to $20b.
A decade earlier, households spent $13.4b on transport collectively.
The numbers are pulled from Statistics NZ’s final consumption expenditure (FCE) calculations, which shows the cost of transport has been rising steadily since 1994.
A Deutsche Bank report said Auckland public transport users spent an average of $174.51 a month, making it the third most expensive city to commute in, after London and Dublin.
New Zealanders’ spending on transport is set to continue to rise as Auckland implements an 11.5 cent per litre fuel tax and councils in other cities look to follow suit.
Post prices and goods like food may become more expensive too as freight firms who transfer goods around the country will incur the extra tax and pass it onto consumers.
