"He was particularly interested in our cultural facilities and the way our unique Maori heritage and living culture are so accessible for visitors to experience.
"We were delighted to have the opportunity to establish links with Ambassador Gilbert. Having an advocate for our city in the US Embassy could potentially help open new doors to the important American tourist market," said Mrs Chadwick.
"The ambassador said he was looking forward to returning in the future, when he had more time, to see more of our city and the district's attractions."
President Barack Obama nominated Ambassador Gilbert as United States Ambassador to New Zealand and Samoa on 6 January 2014 and the US Senate confirmed his appointment on 12 December. He was sworn in by Vice President Joe Biden on 7 January 2015.
Ambassador Gilbert presented his credentials to New Zealand Governor-General Sir Jerry Mateparae in Wellington earlier this year.
He formerly served as managing director of UBS, the culmination of a distinguished career in finance which included positions at Barclays and Goldman Sachs. From 2009 to 2013 he served as the Deputy National Finance Chair for the Democratic National Committee.
