I can tell you that the off peak train fares from Wellington - Johnsonville are due for an increase from 1 September.
As someone who uses both the rail & bus system several times a week, the small increase from $2 to $2.50 for the train is quite acceptable.
(Im assuming the peak rates will go from $3.50 - $4.00)
You can get from the Railway Station to Courtney Place for $1 on the bus.
No wonder i've noticed a big increase in passengers on both, it's so cheap.
Parking is expensive, even ignoring the rising price of oil.
No wonder i sold my car 4 years ago & moved into the City!
