Gap Cache was around from Winter 2015 until Autumn 2017. A cross between the outdoor hobby of Geocaching and its retro-equivalent Letter Boxing, Gap Cache was a treasure hunt that involved visiting eight inspiring gaps in the inner-city where you could enjoy gardens, make music, play sport and fix bikes whilst in search of a letterbox, box or a secret door that held treasure and a clue about the site.

Letter boxing is a hobby-pursuit invented on Dartmoor in 1854, which became popular in the 1970’s and is said to be the predecessor to Geocaching. There are over half a million Geocaches worldwide in over 100 countries with six million users. There are even 1291 geocaches in Christchurch!

Caches were situated on sites where projects were maintained by Gap Filler, Greening the Rubble and RAD Bikes.

We ran our first Gap Cache in 2015 with six locations and six letterboxes decorated by Year 8 student leaders from Selwyn House School as part of a community art project. The letterboxes were six of 1000 salvaged from the residential red zone and looked after by the Avon Otakaro Network. The remaining letterboxes will be used in a future art installation.
