Hundreds of thousands of Auckland households can expect an increased dividend payment of $345 in late September from the community trust that owns most of Vector.
The Auckland Energy Consumer Trust has 318,000 beneficiaries and its annual dividend will increase from $335 to $345.
Trust chairman William Cairns said the dividend boosts Auckland's economy by more than $100 million, with a significant portion of the money being spent with local businesses across the city.
"We know this dividend makes a difference to many in our community - we discovered in a recent survey that more than 60 per cent of Aucklanders said their family needs their dividend to meet the rising costs of living in Auckland," he said.
The dividend distribution, which is New Zealand's largest, comes from AECT's majority shareholding in Vector, and has contributed more than $1 billion to Auckland since AECT was formed in 1993.
