That means the 33-year-old Arn is now a chance to take on New Zealand's best in Marina Erakovic, who will be the only Kiwi in the classic and is drawn to face one of the four qualifiers.
Hayman still drew a lot of satisfaction from her experience and her victory on Saturday, beating Golder 7-5 6-1.
"Was great to get some revenge, as lost to Imogen [in the New Zealand Championship quarterfinal] last week.
"I stepped up and played aggressive tennis, still room for improvement though.
"Served well, first serve scored me a few points. Some days the serve can be on, some days off.
Hayman played on the centre court at the centre on both days, marvelling at the atmosphere.
"This whole experience and opportunity has been absolutely amazing, I am soaking it all in.
"Has been great having Paige up here too. Just the experience and atmosphere young Kiwi players need to be in and learn from."
Hourigan had a tough proposition to face when she drew Simmonds, ranked 177 in the world in October, for her first round opponent.
The 20-year-old Simmonds had won ten singles and seven doubles titles in her career so far.
She proved too strong for the 15-year-old Hourigan, winning 6-0 6-3.
