Wai Manawa / Little Shoal Bay Mini-Shoreline Adaptation Plan (SAP)

About the Wai Manawa / Little Shoal Bay mini-SAP

Wai Manawa / Little Shoal Bay is a reserve on the north shore of Waitematā Harbour. The Wai Manawa / Little Shoal Bay Mini-Shoreline Adaptation Plan (SAP) covers the shoreline of Wai Manawa / Little Shoal Bay.

As a ‘mini’ SAP, the Wai Manawa / Little Shoal Bay SAP focuses on a single coastal reserve area within the wider Waitematā Harbour West coastal areas.

Wai Manawa / Little Shoal Bay was chosen for a mini shoreline adaptation plan because of:

• its value to iwi and local communities
• its exposure to coastal hazards.

This mini-SAP provides options for managing this part of the coast and reserve in the years to come.

To help us develop a plan for this area, we used:

• coastal hazard data
• climate change forecasts
• values from manu whenua
• input from infrastructure providers
• input from the local community.

The strategy for this mini-SAP

The high-level strategies for the Wai Manawa / Little Shoal Bay mini-SAP were guided by mana whenua principles and wider community engagement.

Once the Waitematā Harbour West SAP is developed, it will include the high-level strategies recommended by the Wai Manawa / Little Shoal Bay mini-SAP.

These strategies include:

• performing additional studies to understand the effects of both saltwater and freshwater
• raising local bunds and upgrading stormwater pipes to reduce car park flooding
• shifting and raising the cricket pitch to the west to preserve recreational spaces and plantings
• installing non-return valves on stormwater pipes to reduce flooding from high tides (does not include larger flooding).
• investigating options to reduce flooding through the beach access ramp
• investigating the benefit of existing shoreline interventions.
