Kiwi Abhinav Manota lost in the men's singles, going down in straight games to Sri Lanka's Niluka Karunaratn.
Manota offered no excuses, paying tribute to his opponent while also espousing the virtues of the tournament.
"It was just him, he played better than me today and I couldn't keep up with the pace, I think it was just a bad day for me.
"Overall, I am happy with my performance, but it just wasn't my day today."
It was a similar story for the young men's doubles pairing of Oscar Guo and Dacmen Vong, as they were defeated in straight games by Thailand's Isara and Phuangphuapet, the fourth seeds winning 21-12, 21-15.
17-year-old Guo was clearly disappointed to lose the match but took plenty from the week.
"I was pleased with how we played and managed to impose our game into the rallies and give them a good fight. We need to go away and work on our strength and finishing rallies, but we have many years to keep coming back to play at this tournament."
Quarterfinals get underway at the North Shore Events Centre on Friday at 5pm.
