What Sage Doors does

Sage Doors Ltd is a New Zealand family-owned cabinet door manufacturer founded in 1982 by John Posthuma. The company designs and produces custom cabinet doors, panels, roller doors, and complementary products (Alphatape laser edgetape, FlexiPanels, Beaded Decorative Panels) for cabinetmakers and joinery businesses throughout New Zealand. Its product portfolio spans edged doors under the Invisedge, Acrygloss, Acrymatte, Timbalook, Lookcrete, and Textaura brands; profile doors under Optidoor (paintable HDF) and Opticoat (pre-coated, launched 2025); roller doors for residential and commercial servery applications; and decorative panels. The business operates exclusively B2B with no consumer-direct sales.

Sage Doors runs a state-of-the-art automated factory at 4 Tait Place, Albany, Auckland, equipped with Homag edgebanders custom-spec'd for 1.2mm laseredge tooling, a Wenhomer 3000 Series press for its Opticoat coating line, automated storage and CNC systems, and a proprietary in-house software platform powering the B2B online ordering portal at ordering.sagedoors.co.nz. The portal supports CAD file imports from Cabinet Vision, Microvellum, and Mozaik, live 3D render previews, instant quoting, and auto-save. Sage Doors holds co-development and supply partnerships with German manufacturer MKT GmbH (Alphatape), Austrian acrylic supplier Senosan, Belgian producer Unilin (Master Oak), and German machinery builders Homag and Wenhomer. The company was the first in New Zealand to manufacture doors using laseredge technology, introduced locally in 2013.

Revenue is generated through quote-based B2B sales to New Zealand trade accounts with no minimum order quantities, an online ordering portal, and a nationwide showroom display network. Lead times are 4 days for stock products and 6 days for Opticoat. Sage Doors is privately held by the founding family, with no disclosed external funding, subsidiaries, or parent company; John Posthuma remains involved and his children now participate in operations.

Others
