"We were really impressed with their ability to cater for all our requirements from age grade and referees through to the Steamers.
"The team at Samurai have already shown us innovation and a willingness to promote our brand with quality apparel and we are looking forward to working with them."
Samurai director Helen Clarke echoed those sentiments.
"The team at Samurai Sportswear are excited to enter into a long-term partnership as apparel sponsor with the Bay of Plenty Rugby Union," said Clarke.
"Bay of Plenty is an energetic and innovative union which fits extremely well with Samurai's cutting-edge kit design. We can't wait to watch the Bay teams and referees take to the field in their new Samurai gear."
