Waiting for him was an invitation to play in the South Beach International Amateur (SBIA). That is South Beach, Miami, and it is an event for the world's leading amateur golfers.
It is a big break and possibly McEwan's last opportunity to make the most of his undoubted ability.
The 32-year-old's game has really progressed over the past 18 months, which is ironic, given he finds it difficult to fit in enough practice.
He is engaged to Shannon Lobb and the couple have a 1-year-old son, Jordan. With a young family, it is hard to justify time spent on the golf course. He has to fit practice in during his work lunch break.
But that new appreciation has seen his world amateur ranking climb to 178 and, with it, an opportunity to play in the SBIA.
''I didn't even know I had a ranking, to be honest,'' he said.
''It is just determined on your placings in the events you play [during the past year].
''But it is a big deal. I haven't played an international event in probably eight or nine years and I can't wait.''
The event is being staged at the Miami Beach Golf Club and Normandy Shores Golf Club and begins on December 19.
The world's top 198 amateurs have been invited. After two rounds, the top 72 players progress to the final two rounds and will battle for the title.
There is no prize money at stake but plenty of prestige up for grabs. A good performance could help McEwan launch a professional career.
''I'm 32 now, so I'm not going to get too many more opportunities,'' he said.
''It would open doors big time if I did well. I see it as, not a last chance, but it is getting near it. I've got to just keep going now.''
McEwan expects some very tough opposition and making the cut will be extremely difficult.
''The quality of the field is not going to be too far away from the likes of a US Amateur.''
He investigated the course online and noted there were plenty of water hazards. Accuracy will be key, which should suit his game. He relies on consistency and getting the ball in good areas rather than blasting it another 20m or 30m from the tee.
The event will also be expensive. With return air fares, it is going to cost about $7000. That money will have to be raised. He has had good support from businessman and former All Black coach Laurie Mains.
''He has got me to a few events around New Zealand, which has exposed me to this opportunity.''
