Kelleher said the final amount investors will receive is yet to be determined as it was dependent on the wind-up costs and any investment income earned after October 31, 2020.
ANZ announced in August last year that it would stop taking new investments and look at winding up the scheme due to low interest rates reducing the prize pool.
It had $3.3b invested with around 1.2 million bondholders when that decision was made.
Bondholders were then given until October 31 to cash in their investment or face waiting up to a year to get the money back with the possibility of getting a bit extra.
Of the $3.3b, $2b was cashed in early by around 170,000 bondholders
The remaining investors will receive the final payout in the second half of this year.
