There's growing evidence Kiwis are embracing US-style tipping culture.

New data from financial information site, Banked, says 47 Kiwis approve of tipping- and at least 60 percent of Kiwis sometimes leave tips.

Restaurant Association President and Monsoon Poon owner Mike Egan says customers like to show appreciation for enthusiastic or knowledgeable workers. 

"When you give good service, you sort of invoke the emotional reciprocation. They thought the staff member knew all about the menu, and was great, and made everyone laugh, and was on to it- and they wanted to reciprocate."
