He then paid tribute to the emergency service worker and disaster response workers. He said Christchurch had shown great community spirit but "heart" also needed professional trained response teams to help it thrive.
At the end of his speech he morphed into Arnold Schwarzenegger and promised "I'll be back".
He also held meetings with Mr Key and Mr Little. While Mr Key is a self-declared monarchist, Mr Little said he had made his own views known to the Prince in "a respectful discussion".
Mr Key also clearly tried to make the Prince feel at home by talking about that favourite topic of many British people: the weather. The Prince's visit has included hail, floods in Wellington and tornadoes.
Earlier in the day, the Prince visited students at Southern Cross Campus in Mangere and visited the Middlemore spinal unit. At the unit's gym, he was presented with an All Blacks shirt, which had "P Harry" and the number 15 on it.
The Prince also visited Turn Your Life Around, a youth development programme for children, young people and families to reduce and prevent youth offending.
He played a young man at table soccer before painting his own hand purple to contribute to the handprint wall. He quickly dashed across the room to plant a purple handprint on the head of a visiting British photographer.
"You know why I did that," Prince Harry said, laughing.
The handprint could have been retaliation for the photographer's comments on breakfast TV about Prince Harry talking about going bald like his father Prince Charles.
