Autumn at the Groyns. Christchurch NZ by Bernard Spragg. NZ Via Flickr: Named after the large concrete blocks that jut out into the Otukaikino Creek, The Groynes is a recreational area just north of central Christchurch, with the creek as its central feature. Cut off from the Waimakariri River during work in the 1930s, the creek now forms several lakes and waterways through The Groynes. Families can enjoy the pedal powered boats which can be taken on the water, or enjoy watching model boats sailed by the local club. Trout fishing is allowed in some of the lakes, but anglers must get a permit first.
