We recommend you use the latest Internet Browser from Microsoft Internet Explorer or Mozilla Firefox as this will offer you the best performance and security using 256 bit encryption, which is the highest commercially available encryption strength in use today. However if you have an older version of a browser we can still guarantee 128 bit encryption using the latest digital certificate from VeriSign, which we provide for your protection. 128 bit encryption is currently the NZ health sector standard. For the best experience, performance & protection we recommend Microsoft Internet Explorer version 9.0 or later.
