"The company has returned a $15.4m dividend to the trust this year. This means the direct financial benefits consumers have received from trust ownership since 1999 will be more than $172 million.
"Hawke's Bay power consumers have told us very clearly they want the dividend distributed directly back to them and this is what we are doing."
The cut-off date for determining who is eligible for a payment had been set at September 30, 2018.
"All those who are connected to the network on that date will receive one payment per connection, with a maximum of three payments for any one customer.
"Every year there is a handful of customers affected by this date. Some people commence a new connection within days of the cut-off and therefore are not eligible to receive a payment. For others it works in their favour."
Cheques will be posted out in batches starting on the week of November 17.
Kirton added this would be the last year cheques would be the only means of dividend payment.
"Trustees have recently explored the option of distributing the dividend by direct credit to bank accounts. The cost involved in setting up and maintaining this facility is considerable and will have to be met out of trust funds. Trustees will be consulting consumers on this option in time for the 2019 distribution to ensure this is understood."
The trust was also redeveloping its website to provide easier access to the public.
"Trustees will use the website as a means of communicating with consumers and consulting with them on matters such as dividend distribution and future use of trust funds. They acknowledge that not all consumers have access to the internet, so paper-based consultation will also be provided."
Kirton said the trust was very pleased with the performance of Unison.
"Overall it has been a very successful year. The company is in a strong position."
