Mr Shaw said the tree decorators say while it may not be supernatural, it is a surprising coincidence the image was formed.
"They did not plan for any image other than a Star of David, which is the national symbol of Israel, on top of the tree," he said. "They were unaware that Israel was at war in Gaza. Is this a message to pray for peace?"
Mr Shaw said Marian apparitions are often named after the town where they are reported, or the colloquial name given to Mary on the occasion of the apparition.
"Could this be the Blessed Virgin of Kaikohe, the Madonna and Child or Te Whaea o te Ao?
"We don't know for sure that it is [a Marian apparition], but who knows, people may flock to Kaikohe to see for themselves."
Kaikohe is gearing up for Christmas, with organisers taking on the project to uplift Kaikohe people's spirits and kick off the inaugural Shine Kaikohe festival.
Earlier, when the Christmas tree lights were tested on Wednesday night, Kaikohe couple Jade and Kelliasta Baker renewed their wedding vows beneath the tree.
Mr Shaw said the Bakers had been planning to renew their vows in any case, but the lit-up tree provided the perfect romantic setting.
