The twins Olivia and Mackenzie Smith have been training at the Hāwea kyokushin dojo since it opened in 2015 by Tania and Lachy Brett.
The latest grading was a five-hour test which consisted of self-defence techniques, traditional kata, leading a class of more than 50 karateka (experts), tameshiwari: breaking boards and 25 rounds of 1.5-minute contact fights.
Mackenzie Smith said it was pretty nerve-racking as there was a lot of unknown variables during the grading.
"There was quite a bit of pressure when people started arriving but later on in the grading there was a great atmosphere of support from everyone."
"It [karate] has been amazing for my confidence and integrity throughout the years," she said.
"Their achievement is not only a personal triumph but also a proud moment for Hāwea Karate, their parents and the wider community."
"Kyokushin is renowned worldwide as a demanding, full-contact style of karate and the grading truly tested every aspect of their training," she said.
Olivia Smith said the pair have been attending karate lessons since age 4 and their parents have encouraged them to continue.
"I have gained a multitude of skills and abilities that help me in everyday life."
"[The grading is] designed to test you, not just physically but mentally, it tests your will power not to quit, and it certainly did," she said.
The twins agree there is still learning to be done and this is only the beginning of their journeys as karateka.
