If you are an existing shareholder in one of the NZX listed companies available to invest in via ShareMeUp, you are able to see your total number of shares you hold in the Registry tab.
These balances are retrieved directly from the share registry MUFG Corporate Markets when you add your existing CSN Number to your ShareMeUp account.
Any purchases through ShareMeUp in future will be reflected through an increase in the balance.
The registry balances are refreshed every night.
