This hymn was written by Shirley Erera Murray, who is in fact a New Zealander, and goes under the title 'upside down Christmas'and will fit to many tnes found in standard hymn books (11,10,11,10)

Carol our Christmas, an upside down Christmas;
Snow is not falling the trees are not bare.
Carol the summer, and welcome the Christ Child,
Warm in our sunshine and sweetness of air.

Sing of the gold and the green and the sparkle,
Water and river and lure of the beach.
Sing in the happiness of open spaces,
Sing a nativity summer can reach!

Shepherds and musterers move over the hillsides,
Finding, not angels, but sheep to be shorn;
Wise one's make journeys whatever the season
Searching for signs of the truth to be born.

Right side up Christmas belongs to the universe
Made in the moment a woman gives birth;
Hope is the Jesus gift, love is the offering,
Everywhere, anywhere, here on the earth.
