The cache is a Barocca container in a small tree on the south bank of the canal.
Canal Reserve Road was first mentioned in the Christchurch Press in 1869, appeared in street directories in 1892 and was renamed Linwood Avenue in 1909.
There was a long-time proposal that Port Christchurch should be established on the Estuary and small craft should bring goods up the canal to Christchurch itself. There are available in the archives the minutes of the Christchurch Canal League meeting held in St Saviour's Sunday School Hall in Sydenham, presided over by the Mayor of Christchurch, Mr C Allison. At that time the population of Christchurch was 70,000 and it was expected that it would increase to 150,000 over the next thirty to fifty years. With the canal in use Christchurch would become the leading commercial centre in New Zealand. Unfortunately the construction of the rail tunnel to Lyttelton scuppered the plans, and the Christchurch Port and allied canal never eventuated.  The canal itself is now a storm water outlet for Eastern suburbs of Christchurch.
Finding the cache involves a short walk regardless of the direction of approach, although swimming across the canal is strongly discouraged! The hiding place is fairly obvious and there is no need to disturb any flora. Keep a close eye on small children because of the proximity to water.
