The search for missing tramper Graham Garnett in Kahurangi National Park has been suspended after extensive efforts failed to locate the 66-year-old, who disappeared more than two weeks ago.

Garnett went tramping in the Baton/Ellis River area of the Tasman park and was expected to return on December 30, but failed to do so.

Police search and rescue Sergeant Jonny Evans said the decision was extremely difficult for all involved, but that the family had been “overwhelmed” by the support of others.

“This decision follows extensive searches of the area and is extremely difficult for all involved,” Evans said.

Garnett’s family has expressed gratitude to everyone involved in the search operation.

“They say that the support and effort from everyone has been very overwhelming for them. Police continue to support the family in their ongoing efforts to bring Graham home and we remain ready to respond if new information comes to light,” Evans said.

“Our thoughts are with Graham’s family and loved ones at this time.”

A Defence Force NH90 helicopter and radar technology were deployed in the search, with efforts focused on spurs and large water systems coming off the Wharepapa/Arthur Range.

Parts of the Baton Valley, including the Wilkinson Track, Baton Saddle and Wharepapa Arthur Range, were closed during periods of the search operation.

The search involved Land Search and Rescue (LandSAR) groups from Nelson, Motueka, Golden Bay and around the country, specialist teams, the Defence Force and Rescue Coordination Centre.

Police previously urged anyone who was in the Baton/Ellis River area from the afternoon of December 26, particularly anyone who was around Flanagan’s Hut, to get in contact.
