Between 300 and 500 volunteers are needed in Whangarei and organisers hope to approach schools, community groups and the public to help out.
Mr Beeche said people could register online at www.fifa.com/nz2015 and become a fan.
Ticket sales, he said, would start at the end of May.
After giving a thumps-up to Toll Stadium in its preparation to host the four matches, the delegation then moved to Springs Flat, Kamo, William Fraser Park and Kensington that will be used as training grounds during the tournament.
Mr Beeche said given the level of enthusiasm and passion for the tournament in Whangarei, football fans were being urged to buy tickets early as organisers wanted everyone to get a chance to see the world's best young players in action.
Ms Martin said the delegation had been hugely impressed with Whangarei.
"The passion and support for this tournament is so evident everywhere you go and on that basis we feel very confident that Whangarei will deliver a great tournament for Fifa in 2015."
The mayor welcomed the delegation and said Whangarei had proved it was capable of hosting such a high-profile tournament.
"The momentum is building and the enthusiasm is coming and everyone's just thrilled to be a part of such an event."
Qualifying teams have been named but the draw won't be known until next January.
The four games in Whangarei are expected to bring in more than $3.5 million to the district's economy and expose it to thousands of visitors and tens of millions of television viewers.
