Karanga Jump Platform establishes a safe and legible point of water entry within Auckland’s inner-city waterfront. Positioned at the edge of Te Waitematā Harbour, the intervention redefines public space by enabling direct engagement between body and water - transforming passive waterfront occupation into active participation.

The design responds to tidal conditions, marine ecologies and the physical realities of swimming within an urban harbour context. The platform is conceived as a precise and sculptural insertion into the existing sea wall - acknowledging the layered marine life beneath and the cultural importance of harbour access in a waterfront city.

The form is driven by the choreography of the swimmer’s leap. The cantilevered platform tapers toward a defined jumping point, guiding movement intuitively while subtly elevating users above the water plane. A permeable balustrade enhances visual connection to the harbour below, reinforcing spatial awareness and safety. Materiality and detailing abstract marine narratives - evoking gills, scales or shell forms - while maintaining structural clarity and durability.

Karanga Jump Platform operates as civic micro-infrastructure and water theatre. It strengthens public awareness of water quality, celebrates urban swimming and demonstrates how even modest landscape interventions can recalibrate the relationship between city and sea.
