How NZ Post Dunedin Solved High-Traffic Vehicle Access with High-Speed Industrial Doors
For NZ Post’s Dunedin facility, keeping vehicles moving is not optional. It’s the operation.
Couriers and trucks cycle through the site consistently throughout the day. At a high-traffic external access point like this one, even small delays compound. A door that’s slow to open, one that requires frequent attention, or one that struggles under the demands of a working postal hub, any of these quietly erode efficiency across hundreds of vehicle movements a week.
NZ Post Dunedin needed a high-speed industrial solution suited to a busy distribution centre. One that could deliver fast access during the day, reliable security after hours, and consistent performance under high-cycle use. Those requirements pointed clearly to a Komby door system.
It’s the kind of challenge that high-speed industrial doors for distribution centres across New Zealand are increasingly being asked to solve.
A Komby door system combines a rapid PVC door and a roller shutter door within a single shared frame. The rapid door handles fast, high-frequency vehicle access during operating hours. The roller shutter provides secure after-hours protection. Both operate through the same opening, making it suited to high-traffic logistics and distribution environments.
Problem
A high-traffic external access point at NZ Post’s Dunedin distribution hub needed to handle constant courier and vehicle movements during the day, secure the building after hours, and sustain that performance long-term with minimal downtime.
Solution
A Komby door system combining a rapid PVC door and roller shutter in a single shared frame, installed following removal of the existing wall structure and preparation of the opening to the required dimensions.
Result
Fast, reliable vehicle access during operating hours, secure after-hours protection, and a high-cycle system supported by an ongoing maintenance programme.
The Challenge: Speed, Security, and Reliability at a Busy External Opening
The access challenge at this site was not unusual for a busy logistics or distribution environment. But all three requirements needed to be met together, and the existing setup wasn’t delivering on any of them well enough.
Speed. With constant courier and vehicle movements throughout the day, the entrance needed to open and close quickly, fast enough to keep traffic flowing without vehicles queuing or waiting at the threshold.
Security. The access point faces public areas. After operational hours, a fast-cycling door alone doesn’t provide the right level of protection. The site needed something more substantial to secure the building when it wasn’t in active use.
Reliability. With the volume of cycles this entrance handles each day, the door system needed to be built for sustained, high-frequency use with minimal maintenance interruption. Downtime at this access point has an immediate effect on vehicle throughput, and therefore on the operation.
The Solution: One Frame, Two Doors
What is a Komby door system?
A Komby door system combines a rapid PVC door and a roller shutter door within a single shared frame. The rapid door handles fast, high-frequency vehicle access during operating hours. The roller shutter provides secure after-hours protection. Both operate through the same opening, making it suited to high-traffic logistics and distribution environments.
A Komby door system combines a rapid PVC door and a roller shutter door within a single shared frame.
During the working day, the rapid PVC door handles the volume. It opens and closes at speed as vehicles move through, cycling repeatedly without slowing the operation. Fast cycle times also limit the amount of air that escapes through the opening, helping maintain internal temperature and reduce energy loss across hundreds of cycles throughout the day.
After hours, the roller shutter takes over, providing a robust, secure barrier at what is, by nature, a publicly exposed external opening.
An intelligent control system manages the operation of both doors, and integrated safety sensors support safe use in a loading area where vehicles and people share the space throughout the day.
From Existing Opening to Finished Installation
This wasn’t a straightforward door swap. Delivering the right outcome for NZ Post Dunedin required proper site preparation before the new system could be fitted.
The project involved removal of the existing plywood wall structure and timber packing to bring the opening to the correct dimensions for the new door assembly. Getting that groundwork right was a necessary part of the installation, not an addition to it.
The result was a clean, fit-for-purpose installation, built to the actual requirements of the opening rather than working around an existing structure that wasn’t suited to the new system.
Worth noting
A door installation in a working facility rarely starts with a blank opening. At NZ Post Dunedin, preparing the site correctly – removing the existing wall structure and sizing the opening to suit the new system – was as important as the door itself. Getting that groundwork right is what allows the door to perform as designed over years of high-cycle use.
Built for the Volume
Any door solution installed at a site like NZ Post Dunedin has to handle volume. The entrance operates consistently throughout the working day, a high number of cycles over the life of the installation.
The Komby system is built for high-cycle use and needs minimal ongoing maintenance. In an environment where unplanned downtime has an immediate effect on vehicle throughput, a reliable entrance solution that runs in the background is a practical part of what the facility actually gets.
Durable construction and strong wind resistance also make it suited to external applications, including the demands of a Dunedin environment. For New Zealand logistics and distribution operations, where many external access points face variable weather and high seasonal vehicle volumes, these characteristics matter.
The installation at NZ Post Dunedin continues to be supported through an ongoing maintenance programme, keeping the system operating as it should.
What the NZ Post Dunedin Project Delivered
The NZ Post Dunedin project is a clear example of what the right access solution, properly scoped and correctly installed, can deliver for a facility under real operational pressure.
The requirements were straightforward individually. Meeting all three at a single external opening, with the right site preparation, is where the detail matters.
For logistics and warehousing facilities across New Zealand managing similar pressure at high-traffic access points, the starting question is the same: does the entrance solution fit how the site actually operates, including everything around installation and ongoing performance?

Is your access point keeping up?
If your facility manages high-frequency vehicle movements and needs a door solution that handles both speed and security, properly installed for your site, it’s worth a conversation.
