"I do not think it is a very strong migration pattern from Spain to NZ," he said.
Mr Goodhall said there was plenty of diversity within the seven students.
"Lucy was adopted by her Spanish parents as a child from Ethiopia. They are very multilingual, speaking Spanish, French and Catalan."
Otumoetai College director of international students Roy Ballantyne said Spanish students did not look to New Zealand when looking to attend school abroad.
"They were very excited to be able to choose so many school subjects and got a little confused."
Aquinas College dean of international students Melissa Gillingham said the students were part of a group of 26 who had been travelling Australia before coming to New Zealand.
She said the students were spread around different schools including Taupo, Rotorua, Hamilton and Tauranga.
"I am really impressed with their language. My Year 13 boy has just slipped into all of his subjects.
"I have even asked him to do a speech at our school assembly after three weeks. The language level and the confidence, the maturity is just outstanding."
The students said they loved everything about New Zealand. "They have wonderful views," said 17-year-old Eduardo Torres, who was attending Aquinas College.
"It is so green," said Mount Maunganui College student Lucy Tabar, 15.
Miss Tabar said she loved Kiwi food. "I have put on 3kgs," she laughed.
The 15-year-old said Kiwi people were very nice but questioned why some people wore bare feet.
"I went to Bayfair one time and saw people walking around with no shoes on, so I took my shoes off too," she said.
The students were yet to climb Mauao or taste a Kiwi meal of fish and chips.
Amaia Elkano, 14, of Aquinas College said going to school was different to Spain.
"It is a lot less disciplined. I can use my phone in class," she said. "The teachers are a lot more chilled out."
Aquinas College's Eduardo Torres also found it interesting that 16-year-olds were driving to school. "In Spain, you cannot drive if you are only 16."
