Brisbane full-back Tesi Niu has signed a new deal that will see him stay at the club until the end of 2021.
The 18-year-old made his NRL debut earlier this season after making his international debut for Tonga last autumn.
Broncos chief executive Paul White said: “Tesi is a fine young man and really exciting player who has come through our elite development pathways – we have known him since he was a 12-year-old and he has always impressed us with his commitment and hard work.
“He displays the values and character we want here at the Broncos and we are really excited that he has chosen to stay with us as he develops his NRL career.”
Brisbane coach Anthony Seibold added: “Tesi has got a fantastic work ethic, he’s had to work very hard to get to where he is right now and he is always extremely diligent with his preparation.
“The players and coaching staff are really fond of Tesi, he is a very polite and respectful young man with a great attitude – and is exactly the type of player we want at the Broncos.”
