Prince George's new nanny has made her first public appearance since taking charge of the royal baby.
Spanish Maria Borrallo, 43, was hired less than a month ago.
She was pictured for the first time with the royal party as she got off the Royal New Zealand Air Force jet after it landed in New Zealand yesterday.
Miss Borrallo's introduction to her new job will be to keep her energetic eight-month-old charge fed, watered, rested and happy - while coping with jet lag.
She will also take full charge on at least two nights, first this Sunday when they will go without him to Dunedin, and then on 22 April when they visit Uluru, or Ayer's Rock.
But Miss Borrallo has been well trained for the job, having been taught at the prestigious Norland College, where fees cost nearly £13,000 per year.
The internationally renowned nanny school drew up a shortlist of suitable candidates after the Duke and Duchess of Cambridge approached them looking for a nanny for Prince George, from which the royal couple chose the low-key Spaniard.
They decided to hire a nanny after relying on help from the Duchess's mother, Carole Middleton, and the Duke's former nanny, Jessie Webb, 71.
Miss Borrallo, who is thought to be the first foreign nanny chosen to look after a future British monarch, comes from a smart family of high achievers in Palencia, 140 miles north of Madrid.
When her parents, Luis and Maria Teresa, married in a glamorous Roman Catholic ceremony in Madrid in 1967, the wedding was reported in the society pages of Spain's royalist right-wing daily newspaper, ABC.
Miss Borrallo is the only girl in a family of four children, with brothers named Ignacio, Luis and Pablo.
Nicknamed Santa, which means Saint, when she was young, Miss Borrallo was expected to become a nun by childhood friends who said the shy, serious child was a 'good person' with an austere lifestyle who never showed any interest in boys.
The devoutly Catholic family attended Mass nearly every day, and Miss Borrallo had extra coaching from a neighbour to help her overcome her struggles in chemistry, physics and maths for her baccalaureate exams.
Neighbours said the young girl was not a 'short skirt type', and never seemed to go through the typically rebellious teenage phase.
Instead, a passion for children drove her first to take a degree in teaching in Spain, before moving to Britain more than 20 years ago to learn English and pursue a career in childcare.
She is believed to have worked for families in Britain before taking the job at Kensington Palace,
Her mother said recently: "I am very proud of my daughter, that's all I can say. On the personal front, and professionally, my daughter couldn't be better."
