The 'neck' was laid to rest (haka rere) in Hanga Rau - in the 'Bay of Leaves'.

At the top of the World Tree there surely must be lots of leaves (as many as the stars in the canopy) and according to myth this place was occupied by a little piece of wood which was used to kill Balder:

... Hercules first appears in legend as a pastoral sacred king and, perhaps because shepherds welcome the birth of twin lambs, is a twin himself. His characteristics and history can be deduced from a mass of legends, folk-customs and megalithic monuments. He is the rain-maker of his tribe and a sort of human thunder-storm. Legends connect him with Libya and the Atlas Mountains; he may well have originated thereabouts in Palaeolithic times. The priests of Egyptian Thebes, who called him Shu, dated his origin as 17,000 years before the reign of King Amasis. He carries an oak-club, because the oak provides his beasts and his people with mast and because it attracts lightning more than any other tree. His symbols are the acorn; the rock-dove, which nests in oaks as well as in clefts of rocks; the mistletoe, or Loranthus; and the serpent.

All these are sexual emblems. The dove was sacred to the Love-goddess of Greece and Syria; the serpent was the most ancient of phallic totem-beasts; the cupped acorn stood for the glans penis in both Greek and Latin; the mistletoe was an all-heal and its names viscus (Latin) and ixias (Greek) are connected with vis and ischus (strength) - probably because of the spermal viscosity of its berries, sperm being the vehicle of life. This Hercules is male leader of all orgiastic rites and has twelve archer companions, including his spear-armed twin, who is his tanist or deputy. He performs an annual green-wood marriage with a queen of the woods, a sort of Maid Marian. He is a mighty hunter and makes rain, when it is needed, by rattling an oak-club thunderously in a hollow oak and stirring a pool with an oak branch - alternatively, by rattling pebbles inside a sacred colocinth-gourd or, later, by rolling black meteoric stones inside a wooden chest - and so attracting thunderstorms by sympathetic magic ...

... To conclude these enquiries we may say that if Balder was indeed, as I have conjectured, a personification of a mistletoe-bearing oak, his death by a blow of the mistletoe might on the new theory be explained as a death by a stroke of lightning. So long as the mistletoe, in which the flame of the lightning smouldered, was suffered to remain among the boughs, so long no harm could befall the good and kindly god of the oak, who kept his life stowed away for safety between earth and heaven in the mysterious parasite; but when once that seat of his life, or of his death, was torn from the branch and hurled at the trunk, the tree fell - the god died - smitten by a thunderbolt. And what we have said of Balder in the oak forests of Scandinavia may perhaps, with all due diffidence in a question so obscure and uncertain, be applied to the priest of Diana, the King of the Wood, at Aricia in the oak forests of Italy. He may have personated in flesh and blood the great Italian god of the sky, Jupiter, who had kindly come down from heaven in the lightning flash to dwell among men in the mistletoe - the thunder-besom - the Golden Bough - growing on the sacred oak in the dells of Nemi. If that was so, we need not wonder that the priest guarded with drawn sword the mystic bough which contained the god's life and his own. The goddess whom he served and married was herself, if I am right, no other than the Queen of Heaven, the true wife of the sky-god. For she, too, loved the solitude of the woods and the lonely hills, and sailing overhead on clear nights in the likeness of the silver moon looked down with pleasure on her own fair image reflected on the calm, the burnished surface of the lake, Diana's Mirror ...
