A missing British tourist, overdue on the Te Araroa Trail between Nelson Lakes and Boyle River, continues to concern police.
A helicopter was to search the Nelson Lakes area today for Andrew Ian Wyatt, aged 41, of Cornwall, who arrived in New Zealand in November.
He was last seen by a tramper at Blue Lake in Nelson Lakes National Park on or about December 14.
He was intending to tramp to the Boyle Village in the Lewis Pass, where he was due to pick up a food package on December 16, but he never arrived.
His intention was to then carry onto Arthurs Pass where he had another food parcel to collect, police said.
Search coordinators say he may have now left the area where he was thought to be intending to tramp.
Police are appealing for Mr Wyatt to contact them, or for anyone who has information on his whereabouts to contact police as soon as possible.
Police would also like to speak to anyone who has been tramping in the area.
Contact Nelson Police on 03 546 3840 urgently. The Police event number is P015791441.
