In the end she needn't have felt daunted by the occasion.
"The Governor-General, Sir Jerry Mateparae and his wife, Lady Janine, were very warm and welcoming. They had gone to extraordinary lengths to make us feel at ease. At dinner we weren't seated with our partners. Instead we were seated next to people with whom we had something in common.
"I was told that Sir Jerry organises this himself. So on my right I had Dr Christopher Pugsley ONZM, New Zealand's foremost war historian -- history is my subject and of late I've been engrossed with military history.
"On my left was Brother Sir Patrick Lynch KNZM, QSO, a leading New Zealand educationalist. Also at the table was Pike River survivor Daniel Rockhouse, recipient of the New Zealand Bravery Medal for saving another miner after the explosion at the Pike River mine. "EIT's Dr Susan Jacobs MNZM was there as well, awarded for her service to nursing education. They were amazing people, everyone had a story. We could have talked all night."
Sir Jerry had made a speech before dinner. "He said that behind every successful person was a network of support, including family support, and he paid tribute to them."
