However, some councils will continue to fund cheaper fares for select groups.
Here is a look at how much more people will pay for the bus or train in the main centres once the subsidy ends.
Auckland
From May 1, young people aged 13-15, and secondary students aged 16-19, will all see their fares double on buses and trains.
Weekday zone 1 travel will rise from 70 cents to $1.35, zone 2 travel will rise from $1.30 to $2.60, and zone 3 travel will rise from $1.75 to $3.55. Zone 9 travel, at the top end of the scale, will go from $3.35 to $6.60
Children aged 5-12 will no longer travel for free and must also pay those same fares.
Young people aged 16 to 24 who are not eligible for another concession must pay adult fares. That includes under-18s who no longer attend high school.
Their fares will rise from $1.25 to $2.60 for zone 1, $2.20 to $4.45 for zone 2, $3 to $6 for zone 3, and $3.70 to $7.40 for zone 4.
Ferry fares will also rise. Children aged 13-15 and secondary students aged 16-19 will now pay $3.55, up from $1.75, for travel in the inner harbour (between the Viaduct and Bayswater, Birkenhead, Northcote Point, and Devonport). Children 5-12 must pay the same fares.
For those aged 16-24 who are not in school, the fare will increase from $3 to $6.
For travel in the mid harbour (between the city and Half Moon Bay, West Harbour, Hobsonville or Beach Haven), fares will rise from $2.42 to $5.10 for those aged 13-19 and in secondary school. Children aged 5-12 must also pay $5.10.
Youth aged 16-24 who are not in school will see their fare rise from $4.12 to $8.50.
Those with Community Services cards can get 50 per cent off adult fares, while Total Mobility or Blind Low Vision NZ card-holders can get up to 40 per cent off adult fares on buses, trains and ferries.
Tertiary students receive about 20 per cent off adult fares.
Children aged 5-13 will continue to travel for free on buses and trains during the weekends if they tag on and off with an AT HOP card.
Children under 5 do not need an AT HOP card and can continue to travel for free at all times.
Hamilton
The Waikato Regional Council says it has decided to continue the current public transport fare structure and extend the concessions until June 30.
However, from July 1, public transport fares in Waikato will increase by 20 per cent on BUSIT and Te Huia.
From the same day, fares will revert to the previous structure in the region of one standard Bee Card fare and one cash fare regardless of passenger age.
Wellington
Fares for those aged 5-24 will rise from May 1 throughout Wellington.
However, Metlink bus and train fares vary depending on the time of day, and those travelling off-peak can receive a hefty discount.
During peak times (weekdays from 7am-9am and 3pm-6.30pm), those aged 19-24 with a Snapper card will be charged $1.84 for travel in zone 1 (up from 92 cents), $3.02 for travel in zone 2 (up from $1.51) and $4.03 (up from $2.01) for travel in zone 3.
At the most expensive end at the scale, 19-24-year-olds travelling at peak times in zone 14 will pay $15.95, up from $7.97.
However, if the traveller is studying at a tertiary institution, the fares are $1.38, $2.27 and $3.02 for zones 1, 2, and 3, and $11.96 for zone 14.
Those aged 13-16 - or older if still in high school - will also see their fares double. They now have to pay 92 cents for zone 1 travel (up from 46 cents), $1.51 for zone 2 travel (up from 76 cents) and $2.01 for zone 3 travel (up from $1).
Those aged over 16 and not attending high school must pay full adult fares.
Meanwhile, free travel for those aged 5-12 is ending and travellers will now have to pay the same fares as those aged 13-16.
At off-peak times, all fares are half-price for those using Snapper. This remains unchanged, as does the ability for children aged under 5 to travel for free.
Canterbury
Those aged 5-12 will no longer be eligible for free travel across Christchurch, Selwyn and Waimakariri. From 1 May, they must pay $1 per trip on Metro buses and $2 per trip on the Metro Diamond Harbour ferry.
However, youth aged 13-24 years will not see their fares increase. They will continue to pay $1 for bus trips and $2 for ferry trips.
To qualify for the concession, they must pay with a registered Metrocard.
The full adult fare, for those 25 and over, is $2 for the bus and $4 for the ferry using a Metrocard.
Children under 5 will continue to travel free.
Otago
Children aged 5-12 will continue to travel free on buses in Dunedin and Queenstown from May 1 after the Otago Regional Council voted to continue funding the fares.
The half-price concession also remains for those with a Community Services card or on total mobility services. They will continue to pay $1 per one-way trip.
Those aged 13-18 will pay $1.20 for a one-way trip in Dunedin and $1.50 for a one-way trip in Queenstown, up from 60 cents and 75 cents respectively.
For those aged 19-24, the fare rises to $2 per one-way trip in both cities, up from $1.
Travellers must have a correctly registered Bee Card to benefit from the above fares. One-way cash fares for those aged 13-plus are steeper: $3 in Dunedin and $4 in Queenstown.
As in all the main centres, children under 5 will continue to travel free.
