About The Groynes
The Groynes takes its name from the concrete blocks placed along the Otukaikino Creek to manage water flow and prevent erosion. The area originated as part of flood-protection works on the Canterbury Plains and has developed into a public park focused on family recreation. Christchurch City Council maintains the site, which includes both the junior fishing lakes and a separate recreation lake.
The four junior fishing lakes are stocked annually with rainbow trout ahead of the Take a Kid Fishing event, with many fish remaining available for ongoing use by young anglers. Resident brown and rainbow trout from the nearby Otukaikino River also inhabit the waters. Fishing is strictly limited to anglers aged 17 and under, with adults permitted only to assist. This setup supports beginners in a controlled, encouraging setting.
Beyond fishing, the park features walking tracks, multiple playgrounds, shaded picnic spots and a large dog exercise area. Boat hire operates on the recreation lake during summer weekends. The combination of water, open space and facilities makes the site suitable for full-day family visits without needing to travel far from the city.
Fishing at The Groynes
Junior anglers aged 17 and under may fish the dedicated lakes year-round. A valid New Zealand Sports Fishing Licence is required, though it is free for children under 12. Simple bait such as worms or PowerBait is effective for the stocked trout. Parents and caregivers can help with casting and landing fish but must ensure the child remains actively involved. Regulations are set by Fish & Game and the Christchurch City Council; check current rules before visiting.
Other Activities and Facilities
Walking tracks wind through the park and alongside the creek, offering easy scenic strolls. Three playgrounds and numerous picnic tables with barbecues cater to families. A dedicated dog exercise park allows off-lead play in designated zones. On summer weekends, non-motorised boats can be hired on the recreation lake next to the main play area. Toilets and ample free parking support day visits.
Access and Getting There
The Groynes lies just off the Northern Motorway route, with clear signage from Johns Road between the airport and Belfast. Large free car parks are located near the playgrounds and picnic areas. Public transport options are limited, so driving is the most practical choice when carrying fishing gear or family supplies. The park is open daily from dawn until dusk.
