Hastings belongs to the region of Hawke's Bay, one of the sunniest parts of New Zealand.
This was the bus we spent about 7.5 hours on it to reach Hastings from Aukland.
Some of the reliable public transports on road are:
1. Newmans Coach Lines
2. Intercity Coach Lines
Same as Intercity, nakedbus.com offers the cheapest ticket price starts at only $1(booking fee excluded). You may get it if only you manage to book early and good luck enough, as they have very limited seats offered at this price and you get to pay more if all the cheapest tickets are taken.
