"And you should have heard the reaction of staff here in the branch too.
"I think we made more noise than Aaron."
Thrilled with his win, using some to repay some of his personal loan a bit quicker than planned and putting some money aside for the freezing works off season, Aaron has also had a "bit of a splash out".
But that spending on a bit of fun didn't include a ticket in last week's $44 million Lotto draw.
"I thought this win was enough luck for me, so I didn't buy a ticket," he said.
The promotion was open to any NZCU Baywide customers who took out a personal loan of more than $2000 between September 12 and October 31. The winner was drawn randomly from all those who had loans approved and drawn down across the NZCU Baywide 14-branch network as well as online applications.
Another $5000 cash prize is now up for grabs in a second prize draw for any customer who is approved for and draws down a personal loan of more than $2000 by December 16.
