It’s silly season again, where holidays collide with pre-February weather. An annual bubble of SAR-related incidents has hit the news-wires in the past few weeks.

One story in particular first came out on January 2nd. It concerned a search for “five young trampers” in the Tararua Range who planned to walk to Penn Creek Hut via Table Top, then follow Penn Creek and the Otaki River back to Otaki Forks. They were reported overdue, and it was resolved quickly after Police sent a helicopter into the range, only to discover the group completely safe at Penn Creek Hut, drying out gear having turned around.

For some time now, especially since the old track which sidled above Penn Creek was washed out, the route has become notorious for parties becoming stuck and requiring rescue. This group had not required a rescue, but that information was not available and so a search operation was launched anyway.

Search officials use many factors to decide how likely it is that somebody might need help. There’s not enough reported context to fully explain why a search was launched when it was. My guess, however, is that a combination of “5 young people” plus “Penn Creek” plus “several waves of incoming torrential rain and certain flooding”, and very possibly some additional information, left doubts about the party’s ability to cope with circumstances on its own, and led to a conclusion of a reasonable chance that the group might be in trouble.

From the moment of that conclusion, the situation needs to be resolved as urgently as possible. If a helicopter had not found 5 relatively-happy people drying their gear in a hut, it might have been necessary to inject ground teams into some awkward parts of Penn Creek, and lift them out again, during a short window of time prior to likely floods.

The reports of this incident inspired an untypical amount of attention in social media. One of several examples is on Federated Mountain Club’s Facebook page. The main discussion, however, was neither about the details of the trip nor the actual search operation. The most common angle of interest has been on the comments from police afterwards.

Specifically, Police spokesperson Andy Brooke was quoted as saying “it is a timely reminder to take at least two forms of communication with you when venturing into the outdoors.”

The discussion has probably been prompted because this statement isn’t so much a recommendation to consider if taking communication is appropriate as a directive to take communication, on an implied assumption that the necessity of communication is now a foregone conclusion. The two particular forms of communication with Mr Brooke propsed were a PLB, and a Satellite Communication Device such as a SPOT or inReach.

It’s sparked some informal debate about at least two things: (1) Whether a PLB would have made a difference in this situation given that the party had no actual emergency, and (2) whether parties should be obliged to carry any communication at all.
