The international model is no stranger to putting on displays in bikinis.
Back in 2000, she led support for Team New Zealand in the traditional America's Cup race.
Clad in a patterned blue bikini, the beauty was pictured waving the flag as she perched her legs on either side of a large boat.
Late last year, she revealed to Instagram fans that she would be spending her first Christmas in New Zealand for 23 years.
Some eight weeks later, she's still residing here, regularly posting images that show her embracing the country's beauty.
Rachel began her career at just 17, with 2017 marking her 30th year as a working model.
