ANZ also confirmed that it had withdrawn from discussions with US investment giant Kohlberg Kravis Roberts & Co (KKR) about a potential acquisition of accounting software firm MYOB.
The bank also issued a quarterly business update to go with details of its capital raising announcement.
"This was a pleasing quarter where all our businesses performed, particularly our home loan business in Australia," ANZ's chief executive Shayne Elliott said.
"While rising inflation and interest rates are starting to impact some customers, household and business balance sheets remain strong and with a collective provision balance of $3.8 billion we are well-placed to continue to support economic growth into the future," he said.
In New Zealand, the bank had "delivered disciplined growth across core products".
ANZ shares are on a trading halt while the rights issue gets underway.
