Contacts can be imported into Kahua.  Export your contacts from any database into an Excel spreadsheet.  The Kahua Contact Import Plugin will allow you to create an import spreadsheet from any excel file.  That spreadsheet can then be imported into the Kahua Contacts app. 

Download the plugin from the attachment below.  You will need administrator rights on your PC to install the tool.  After installation is complete, open the Excel file with the Contacts you would like to import and click "Create File For Import" on the Excel Add-Ins tab.
