Lockwood Smith has kicked off his new career at High Commissioner to Britain in typically flamboyant style, opening a function with the theme song to an Australian children's TV show.
The veteran MP, who was Speaker until January, this week hosted a function in the penthouse of New Zealand's High Commission in Haymarket, famed for its views of London.
According to the website nznewsuk.co.uk Smith "brought the house down" after beginning his address by singing the theme of "Here's Humphrey" in its entirety.
First aired in the 1960s, Here's Humphrey was one of the most popular television shows for preschoolers of its time. It ran for more than 40 years.
Despite many of those in the audience being media, no footage of the performance has emerged.
Smith then reportedly "spoke proudly about how well things are going for New Zealand currently" and expressed his commitment to furthering British-New Zealand relations, especially in the lead-up to the centenary of the First World War.
He praised the media for its reporting of the Canterbury earthquake in Britain.
Smith was replaced as Speaker by David Carter and as an MP by Aaron Gilmore, who has also been attracting headlines, most recently because of his actions in a Hanmer Springs hotel last weekend.
