The campsite pass can be upgraded to a hut pass after 6pm on payment of the difference. Passes are available at hostels, outdoor equipment shops, visitor centres, DOC offices in the Nelson and West Coast regions and from private bus operators. Back country hut tickets and annual passes are not valid on the track. Passes not purchased before starting the walk will be charged at premium rates. Premium rates apply to all passes purchased on the day from hut wardens and other DOC staff on the track.
Heavy rain can occur with little warning and even small streams are dangerous in flood.
The downs are exposed to cold winds, thick mist and rain. You will also need a portable cooking stove and fuel. Boots are the recommended footwear for the Heaphy. Giardia has not been found in waters along the track but it may still be present. To avoid giardia water should be boiled, chemically treated or filtered.
