Police want to know who took a kayak and a range of survival equipment to Rangitoto Island - and left it there.
A distinctive 3.5m long Ocean Kayak, originally yellow but painted blue and black in the style of Navy camouflage was found stashed above the high tide mark by people carrying out weed eradication at Flax Point in early March.
The Department of Conservation was advise and yesterday they passed the information onto police.
Senior Constable Anthony Flannagan said it was possible that whoever took the kayak to Rangitoto Island is still there.
