New Zealand's backcountry is beautiful, dense and unforgiving — and for a handful of people, it has been the setting for the worst days of their lives. Writer John Summer has spent time with survivors of getting lost in the bush for his book Green Sea: Lost in the New Zealand Bush, and the stories he gathers are a useful reality check for anyone planning to head beyond the trailhead.

Summer's starting point is personal: his own worst nightmare is the idea of being lost. Rather than writing a how-to manual, he interviews people who have lived through it — trampers and hunters who wandered off-track in New Zealand's native forest and had to find their way out, or hold on until rescue. Their experiences are the raw material of the book, and they underline how quickly an ordinary day walk can unravel: a missed junction, fading light, thick undergrowth that all looks the same.

What makes the book interesting beyond survival lore is how Summer reads 'lost' as more than a navigational state. He explores it as a metaphor for other kinds of disorientation — addiction, a midlife crisis, the sense of not knowing where you are in your own life. That framing turns what could be a grim catalogue of mishaps into something more reflective, and it explains why the book has struck a chord with readers who may never lace up a hiking boot.

For travellers, though, the practical takeaway is clear. New Zealand's bush is famously easy to get lost in: the forest canopy blocks long-distance views, tracks can be muddy and poorly marked, and weather changes fast. The survivors Summer speaks to are the ones who came back — many others in similar situations have not. Local organisations like LandSAR, the volunteer search and rescue network, respond to hundreds of incidents a year, and the standard advice they echo is simple: tell someone your route and expected return time, carry a map and compass or GPS (and know how to use them), pack extra food and warm layers, and if you do become disoriented, stop moving rather than pushing on and getting further from help.

Who is this story for? Anyone thinking about hiking in New Zealand — from the Great Walks to remote backcountry routes in Fiordland, the Ureweras or Kahurangi. Reading accounts of people who got lost, and lived, is a far better teacher than a checklist alone. Summer's interview about the book is also available to listen to, if you'd rather hear the survivors' stories in their own voices before your next trip into the bush.
