Multi-dwelling units

If you are developing an apartment, retirement home, office block or multi-use block with mixed commercial and residential premises, we recommend you wire the building for fibre,  the best available telecommunications solution.

In many parts of the country two networks are in operation – copper and fibre. Wherever possible, we recommend installing fibre infrastructure for the best experience. Check out our broadband map to see if your development falls within our completed or planned Ultra-Fast Broadband (UFB) fibre areas.


  1. Check whether fibre or copper is available at the site of your development so you can plan the best internal pre-wiring
  2. Development plans – make sure you include any separate connections needed for elevator alarms, fire alarms or other items that can impact overall capacity
  3. Total number of units and connection required, defined by the number of floors and connection per floor
  4. Any plans to complete your development in stages
  5. Floor plans
  6. Cross section plans
  7. Common service trench plans
  8. Services area plans
  9. Other utility plans
  10. On-site contractor details
  11. Any other information that will help us understand your development

What is the development process for MDUs?
Once the MDU checklist is completed, here is a step-by-step outline of the process that will happen to create the best broadband solution for your multi-dwelling unit development.

The MDU process
1. Provide information
Check the documents off our checklist and send all the information to us via the online form to get the process started.

2. Estimate (Optional - if required)
We develop an estimate based on the information provided to give you an indication of the costs. If you decide to proceed, we will conduct a formal scope and provide a contract and quote.

3.   Scope
We develop a preliminary plan for your project based on the number of units/dwellings and connections. We then assess what needs to be done to service and reticulate your MDU.

4.   Provision of contract and quote
We provide you with a contract. This includes information about what we intend to do and any actions that you need to complete, along with a quote that is valid for 90 days. Click here to see how costs are calculated. Any costs associated with any work outside of the boundary of your development will be included in this quote.
5.   Acceptance of contract and quote
You accept the quote and the work required by signing and returning the contract to us, along with any associated payment in full. We’re unable to begin work on your development until the signed contract and payment are received.

6.   Design
Our service company will then begin work on the detailed design so the interior build can begin. For MDUs, how fibre is distributed throughout your development can change dependent on its type and size; this will be detailed during the design phase.

7.   Build
Chorus will typically supply all materials needed to reticulate your development for fibre and retains ownership of this infrastructure – you can find more information about reticulation and wiring here. Installation of these materials within your development is your responsibility and cost, but our Service Partner will work with you during the process. Once the initial build is complete, our technicians will connect your property to our network, testing the work as well as linking the property with our cabinet or exchange.

8.   Completion
Under the district plan covering your development you may need to provide a certificate of completion to the council to receive your Completion of Resource Consent Conditions (often referred to as 224c Certification). We will provide this certification once all build and quality assurance testing is completed by our Service Partner. Once the network has been installed and commissioned, ongoing repairs and maintenance of the network becomes our responsibility.

As part of this step, we also confirm that any required Easements are in place. For more information visit our Easements page.
