His performance on the world stage last year and now this notable win makes Hughes a firm favourite to make the U21 New Zealand, if not the open grade itself.
"The selectors are expected to announce the New Zealand team in May and I hope I've done enough to make the side," Hughes said.
"The U21 World Championships this year are in the South Island just days before the open worlds. You can be selected for both, but I don't know what their [selectors'] thinking is at this stage. In the meantime, I'll just keep competing as best I can and hope I've done enough.
"It was a real buzz winning the Duncan Dixon."
Meanwhile, on Tuesday Hughes turned his talents to track and field at a Cullinane College sports day winning the long jump with a 5.5-metre leap.
"I didn't do too well in the javelin, though."
