question for jack and other jet setting travellers

[henrybulldog]

looking for a flight from adelaide to auckland in mid march. any particular search engine do you recommend ie webjet/iwantthatflight and do you book 3-4 months in advance or gamble up and hope for a cheap seat closer to the date. atm im thinking air new zealand direct is the most convenient and hassle free option. im very much the anti-balla so a 250 buckaroo difference would be a deal breaker/maker.
