A 40-year-old bus timetable discovered in our old shed. Five buses a day serving Orewa, Silverdale, Dairy Flat, Waitoki, Kaukapakapa, Helensville, Parakai, Wharepapa, Woodhill, Waimauku, Huapai, Kumeu and on into Auckland City.
Cost for the approx 70km trip(!) from Dairy Flat into the city: $1.05 or 78c if you buy a 10 trip concession, but adults pay a child fare if they travel off-peak so this would be 30c on a concession if you leave after 9.00am. From Dairy Flat to the city would have taken approx 1 hour and 40 minutes - not bad considering the circuitous route.
Using the Reserve Bank's inflation calculator, a 30c bus ticket would cost $1.31 today, and the journey on the Northern Express takes about an hour from the Silverdale Station off-peak and costs $6.20 on the HOP card.
So, it's a bit quicker today, more direct, more frequent and nearly five times the cost.
