More than 340,000 Aucklanders are now being asked how they want to be paid their dividend but told payment can't be made by cheque.
They will get their Entrust dividend in late September.
Entrust chairman, William Cairns, says the decision to phase out cheques was made by banks, not Entrust, and that trustees were aware the change would be frustrating for a lot of beneficiaries who had historically opted to receive their dividend by cheque each year.
"After the unprecedented year we've had and in these uncertain economic times, we understand many families and businesses will be relying on the Entrust dividend this year and need it more than ever,'' he said.
