Westhaven Marina’s L pier fully replaced - with a sustainable twist

A second life for Westhaven Marina’s old piers
 
We’re proud to share how materials from the K and L pier replacements are finding new homes and purposes – supporting environmental sustainability and benefiting communities across New Zealand and the Pacific.
 
Instead of heading to landfill, much of the dismantled infrastructure has been repurposed:
 
•    Damaged pontoons went to a Kaipara farm, where they’ve now been repurposed in silo bins and a concrete retaining wall.
•    Timber piles and pile caps were also repurposed on the same farm for fencing and haybarn structures.
•    Remaining concrete pontoons were shipped to Manukau, then loaded onto flat-racks bound for Pukapuka in the northern Cook Islands, where they’ll form part of a new cruising boat facility.
•    Approximately 90% of the timber walers were reused by a South Auckland community garden for planter boxes and edging, with some used to frame a farm shed.
•    100% of the old steel components - including cleat fasteners, pile guides, corner frames, galvanised through rods, and power cables – were sent to metal recyclers.
•    Several pile sleeves were re-ground and recycled into new PE sleeves and pipe.
•    Foam-filled PE plastic pile floaters were among the only materials that couldn’t be recycled and were sent to landfill — a limitation we've addressed with our new, fully recyclable, foam-free pile floaters.
 
We’re thrilled to see so many components given a second life – helping to reduce waste and create positive outcomes both locally and abroad.
