What First Windows & Doors Whangamata does

First Windows & Doors Whangamata (trading as "FIRST Whanga") is a family-owned aluminium joinery manufacturer established in 1998 by Tony and Kirsty Corbett, operating from a single manufacturing facility and showroom at 314 Casement Road, Whangamata, New Zealand. With a headcount of approximately 5, the company manufactures and supplies aluminium windows, doors, and entrance doors — including the proprietary ThermalHeart+® thermally efficient system with Centrafix™ installation, the Klima Series uPVC range, and the AGP double-glazing system — alongside five proprietary hardware ranges (Urbo, Miro, Icon 316-grade stainless steel, Elemental, and Porta) and Dulux powdercoat plus anodised surface finishes. The company is a member of the APL Window Solutions supply chain, NZ's largest window and door manufacturer, which provides access to proprietary product ranges and sustainability certifications (Toitu, Declare, EPD).

The company operates a direct sales and installation model from its Whangamata workshop, serving residential homeowners undertaking renovations and new builds as the primary customer segment, with commercial builders as a secondary segment. Projects span standard family homes to one-off architectural designs, with an explicit coastal-environment specialisation driven by the Whangamata/Coromandel location. Distribution extends beyond the immediate Coromandel region to cover the broader New Zealand market and the Pacific region. Pricing is quote-based with 30-day validity, and the company offers both supply-only and supply-and-installation contracts; quotations are subject to a full site measure and inspection. All products are tested and certified to NZS4211 (Performance of Windows) and NZS4223 (Glazing in Buildings), with a 5-year product and hardware warranty.

Following a 2022 leadership transition in which Sara Watkins took over as Managing Director from founders Tony and Kirsty Corbett, the business has broadened its product range and integrated into the APL Window Solutions supply chain. The company markets primarily through its website (firstwhanga.co.nz), which functions as a product catalogue, project gallery, and quote-request channel. It holds no external funding and operates as a privately held family business with no disclosed parent company or subsidiaries.

Broad incumbents

• APL Window Solutions: APL Window Solutions is New Zealand's largest window and door manufacturer network, of which First Windows & Doors Whangamata is a member. APL supplies the ThermalHeart+, Klima, and AGP product ranges and provides sustainability certifications (Toitu, Declare, EPD) used by this business — making it the most directly comparable entity, though operating at a much larger national scale.
• Kawneer (Arconic): Kawneer is a global architectural aluminium systems manufacturer offering windows, doors, curtain walls, and storefronts. As a broad incumbent in aluminium fenestration with significantly larger scale, it sets competitive benchmarks and specifications that smaller NZ joiners like First Whangamata must meet.

• Altus Windows: Altus Windows is a New Zealand aluminium joinery manufacturer with a comparable regional supply-and-install model targeting renovation and new-build residential projects. Similar product positioning and customer base make it a relevant direct peer for First Whangamata.
• Nulook Windows & Doors: Nulook is a New Zealand manufacturer and installer of aluminium windows and doors for residential and light commercial applications. It competes directly with First Whangamata on aluminium joinery supply, product range, and regional builder/dealer channels across New Zealand.
• Altherm Windows & Doors: Altherm is a New Zealand aluminium window and door brand focused on thermally efficient systems for residential and architectural applications. Comparable product category, fabrication approach, and channel overlap make it a relevant direct peer.
• First Windows (national brand): First Windows is a New Zealand aluminium window and door brand whose ThermalHeart+® system is supplied through the same APL Window Solutions network as First Whangamata. Overlapping product portfolio, network, and NZ builder channel make it a directly comparable peer.

Others
