Mānawa Bay is New Zealand’s premier outlet shopping destination, set within park-like grounds overlooking the mangroves of Auckland’s Manukau Harbour. The precinct required a landscape solution capable of performing in a high-footfall, coastal environment while maintaining a refined architectural presence.

Tiny Anvil supplied a range of commercial steel planters across the site, including bottomless corten cylinders, corten troughs, and black powder coated cubes and columns. These elements were specified to support both the site’s sloping terrain and its structured pedestrian zones, allowing planting to integrate naturally with the landscape while maintaining visual consistency throughout the precinct.

Corten planters were embedded into the landscape to enable deeper root systems, improved drainage, and long-term plant health, while their weathered patina provides a warm, natural contrast to contemporary materials. Powder coated planters were used in high-traffic areas to introduce crisp definition and durability where a more architectural finish was required.

All planters were designed in New Zealand for commercial installation and long-term performance, contributing to a cohesive, low-maintenance landscape that aligns with Mānawa Bay’s 5 Star Green Star Design rating and long-term sustainability objectives.

By using a coordinated range of durable steel planters, the landscape at Mānawa Bay is able to respond to varied site conditions while maintaining consistency, longevity, and a strong sense of place across the property

Bottomless Corten Planters Integrated Into the Landscape

The sloping terrain at Mānawa Bay required a planting solution that could respond to changes in level without introducing heavy retaining structures or visual interruption. Bottomless corten planters were embedded directly into the hillside, allowing planting to connect naturally with the surrounding ground rather than sitting as a separate, imposed element.

By removing the base, these planters enable deeper root systems, improved drainage, and long-term plant health — particularly important in exposed, coastal conditions and large public environments where planting performance must remain reliable over time. This approach reduces water pooling, mitigates stress on plantings, and supports healthier establishment in challenging ground conditions.

Corten steel was selected for its durability and ability to weather gracefully in outdoor environments. As the steel develops its protective patina, it softens visually against native planting and stone, allowing the planter to recede as vegetation matures. Rather than competing with the landscape, the material becomes part of it — providing a subtle architectural frame while allowing planting to take visual precedence.

From a construction and maintenance perspective, bottomless planters offer a practical advantage on large-scale commercial sites. Integrating the planter with the ground below reduces reliance on complex substructures, supports natural soil profiles, and minimises long-term maintenance requirements once planting is established.

The result is a landscape element that feels grounded, permanent, and purpose-built — aligning with both the environmental goals of the precinct and the long-term durability expectations of a high-use retail environment.

A Cohesive Planter Strategy Across the Precinct

Rather than relying on a single planter type, the landscape strategy at Mānawa Bay uses a coordinated range of corten and powder coated steel planters to respond to varying site conditions, circulation patterns, and architectural adjacencies.

Corten planters are used to anchor planting within the broader landscape, particularly in sloped and planted zones where material warmth and long-term weathering support a natural, established feel. In contrast, black powder coated cubes and columns are deployed in high-traffic pedestrian areas, entries, and retail frontages, where a more refined and architectural expression is required.

This combination allows the landscape to transition seamlessly between planted edges and built form, maintaining visual consistency across the precinct while adapting to different functional requirements. Repetition of form and finish reinforces cohesion at scale, while subtle variation supports legibility and wayfinding throughout the site.

The result is a durable, low-maintenance landscape system that supports both the operational demands of a busy retail environment and the long-term design intent of the precinct.

Across Mānawa Bay, planter selection was guided by the need for durability, repeatability, and long-term performance in a high-use public environment. With large pedestrian flows, exposed coastal conditions, and a mix of planted and architectural zones, the landscape elements needed to work consistently at scale without becoming visually dominant.

Standardised planter forms allowed the landscape to be deployed efficiently across the site while maintaining a cohesive visual language. Repetition of material and proportion reinforces continuity throughout.

Material choice played a key role in achieving this balance. Corten steel was used where integration with planting and landscape was prioritised, allowing planters to weather naturally and soften over time. Powder coated steel was introduced in more structured retail and pedestrian zones, providing a crisp architectural counterpoint where clarity and durability were required.

Together, these elements form a coordinated landscape system rather than a collection of individual features. The result is a robust, low-maintenance approach that supports both the operational demands of a major retail destination and the long-term design intent of the outlet.

The Bottomless Cylinder Planter supports deep-root planting by integrating directly with the ground below. Used across Mānawa Bay’s sloping landscape, it enables healthy plant establishment while corten’s weathered finish blends naturally with native planting and stone in a high-use commercial environment.
