Another feature of the portal is the ability for people to message their doctors.
Mr Cocks said short queries would be answered at no charge but doctors could ask patients to book an appointment if a longer consultation was needed. He said the portal was very secure and the data was encrypted.
It requires a login and password, and according to the ManageMyHealth website, uses security measures similar to internet banking.
"It's sort of part of the shared care records [SCR] system ... but it's a stand-alone web-based program," said Mr Cocks.
Most Wairarapa people's health records are already online in the SCR system, which started in 2011 and was designed to allow hospital staff and after-hours GPs to access records from a patient's regular doctor. Masterton Medical, Carterton, Featherston and Greytown Medical Centres, Martinborough Health Services, and Whaiora participate in the SCR system.
The nationwide rollout of portals is being led by the National Health IT Board and 50 per cent of GPs are expected to have a portal by the end of the year.
Mr Cocks said it only gives access to your records at Masterton Medical, not those from previous practices.
The practice also now takes bill payments on its website by Visa or MasterCard.
To sign up for the portal, people can ask at reception for a registration form but must be over 18 and provide an email address and valid ID.
