  • For you to sign dealings, a connection must be made between the Landonline Dealings app and your current Digital Certificate (DC).  
  • Once this connection is made, your browser should remember the location of your DC each time you sign. We recommend using Google Chrome or Microsoft Edge.
  • When your DC is renewed you will need to link your new DC to the Landonline Dealings application. 
  • Only DCs which are on the 2-year renewal cycle can be used to sign in the Landonline Dealings app. 

What to do

  1. Select Choose DC.
    • If you’ve never added your DC, such as if you’re a first-time Landonline user, select Choose Digital Certificate
    • If you’re replacing an existing DC, for example because your DC has just been renewed, then select Change Digital Certificate.
    • A File Explorer/Finder window will open.

If your DC hasn’t been renewed onto a 2-year certificate, you will need to continue certifying and signing in Legacy Landonline. You can still view certifications in Landonline.

  1. Navigate to your DC file location.
    • Navigate to the LINZ Certificates folder, which contains your DC. By default, this will be in your C:\ Drive > LINZ Certificates folder. However, it will depend on your computer.
    • If you can’t find the LINZ Certificates folder, ask your firm’s Trusted Contact or your colleagues to find where certificates are normally stored.
  2. Select your current DC.
    • Click once on the file (the file name should be your Landonline username) to highlight the Digital Certificate.
  3. Select Open.
    • Select Open in the File Explorer/Finder window to choose your DC.
    • Once you have uploaded a DC, File Explorer/Finder should automatically open in the correct folder the next time you need to upload or change a DC.
    • If you try to upload the wrong certificate or an expired certificate, you’ll get an error message.
