Jetstar is having an Easter sale. Lots of the usual cheap domestic routes ($19-$25 O/W flights) and some international.
Rarotonga $129 O/W, $330 Return, from Auckland, $158 O/W, $388 Return from Wellington, AKL->NPE/NSN $25
Auckland to Rarotonga (27 April - 27 June & 8 Aug - 21 Sept) $330 It's tied with the cheapest Raro flight deal from Boxing Day but can't beat the Jetstar Fly Return for Free which were ridiculous prices.
Wellington to Rarotonga, (2 May - 27 June, 8 Aug - 21 Sept, 12 Oct - 26 Oct) $388 Return for most of the dates. Cheapest ever other than the Fly Return for Free sale.
Australia, Bali, Phuket flights are OK in price but nothing great. Phuket for $210 is good but very difficult finding a flight that comes back (once a week it seems) and is not expensive.
Remember these flights don't include baggage + food.
Seem to be more expensive coming back to Raro.
$95 extra required each way if you want to carry any luggage with you.
Good price though given it includes the connecting flights from Wellington to Auckland.
