He has tickets to both of Uruguay's group matches against Serbia and Mexico to be played in Dunedin, and is looking forward to cheering his team on with friends and family.
The 27-year-old Port Otago marketing manager, whose family is from the Uruguayan capital city of Montevideo, moved to Oamaru in 2003 to escape Uruguay's floundering economy.
Erdody went on to study marketing in Dunedin for four years, before moving to Auckland.
He returned to Dunedin two years ago to take up his role at Port Otago. Uruguay is pitted in pool D with Mexico, Serbia and Mali, and plays two of its three group games under the roof at the renamed Otago Stadium.
Erdody, who was on holiday in Brazil last year when Uruguay stunned England 2-1 at the Fifa World Cup, has plenty of faith in Uruguay's under-20 crop of players.
''They have a real strong team,'' he said.
''They have a real direct style of play. They have a lot of good players coming through, who all play professionally in Uruguay.
''I reckon they have got a good shot. The thing with Uruguay, they can beat any team, but you never know.''
One player to watch out for is Gaston Pereiro, a 19-year-old attacking midfielder who has drawn comparisons to the late Brazilian great Socrates.
Socrates was known for his beard, trademark headband and playmaking ability. He captained Brazil at the 1982 World Cup, and scored 22 goals in 60 matches for his country over seven years.
Erdody's father, Nicolas, a former Waitaki Boys' High School teacher, his mother, Maria, and his younger brother, Esteban, will come from Oamaru to support their country.
The World Cup will also act as a farewell for Erdody's sister, Leticia, who is based in Auckland.
She is leaving New Zealand to travel at the conclusion of the tournament.
''We have also got a big group of Uruguayans coming over from Australia. They are hiring a campervan and going all around the South Island,'' Erdody said.
Despite Uruguayan bad boy Luis Suarez often making headlines for all the wrong reasons, the hot-headed striker is Erdody's favourite player.
''Obviously, he's an awesome player,'' he said.
''He comes from a real poor background, so I guess he has got that whole survivor mentality. That kicks in and he needs to win at all costs - he just loses it in the heat of the moment.
''The goals he scores are just amazing.''
Uruguay's opener against Serbia on May 31 is the second match in the first of three double-headers to be held in Dunedin.
The South American nation, which also plays Mexico on June 3, will play a round-of-16 playoff match in Dunedin on June 10 if it finishes top of group D.
