Tickets for the Wellington sevens went back on sale at 3pm today.
They were were taken offline this morning after a problem with the payment system prevented thousands of fans securing their tickets.
More than 7000 tickets were sold before problems began, and there are still about 11,000 available for purchase.
"We apologise again for any confusion or inconvenience this has caused our loyal fans, and we hope they'll come back at 3pm and be successful in getting their hands on some tickets," event general manager Steve Walters said in a statement.
Mr Walters urged people to get in quick, as he expected the re-launch of tickets to take off just as quickly as they had done this morning before the problems occurred.
