But the UK singer hasn't been sight-seeing on his own - he's had a personal guide in the form of Kiwi model Emma Champtaloup.
Champtaloup has modelled all over the world and walked for the likes of Proenza Schouler, Prada and Marc Jacobs, but this summer, she's relaxing at home in New Zealand and showing Smith what our country has to offer.
She's posted photos of herself with the star on Instagram during her travels from Lake Tarawera - her "favourite place" to the Coromandel and more.
She and Smith appear to go way back, and catch up regularly in London having "date nights", visiting Sotheby's - a fine art auction house - and even doing a mannequin challenge.
While relaxing at Lake Tarawera, Smith reportedly boarded the boat of some excited fans who spotted him and realised it was him when they saw his distinctive tattoos.
One fan, Taylor Powell told TVNZ they blasted Smith's hit Stay With Me loud enough to get his attention and he later jumped aboard for some selfies and a chat.
Judging from that and Champtaloup's Instagram account, Sam Smith's having a ball on his Kiwi summer holiday.
