Air New Zealand releases hilarious summer themed Christmas song

International star Ronan Keating and Julian Dennison of Hunt for the Wilderpeople  have teamed up for this clever video with Air New Zealand to celebrate the unique southern hemisphere Christmas. Summer Wonderland, the Kiwi take on Winter Wonderland, swaps out the traditional winter based lyrics for sweaty bro's,  pavlovas, jandals, greeny brown birds and 'dodging heaps of prickles with your nan'. With Julian acting as 'Roman's' music director,  it's a video that's sure to make anyone who's  experienced a Southern Hemisphere Christmas laugh. The video ends with Dennison telling 'Roman' he probably needs to put on 70SPF sunblock. Read: Why Air New Zealand wins airline of the year for the fourth time
