Tasman Rugby Union chief executive Tony Lewis has explained the decision that sees the Mitre 10 Cup side renamed simply "Mako".
Having been the Makos for the past 11 years, Tasman have today confirmed they will be ditching the s at the end of their name.
Speaking to TVNZ 1's Te Karere, Lewis said that the decision was made to honour the union's Maori heritage.
"We've been working with the eight iwi at the top of the South (Island) for the past 18 months," he began.
"It became clear from those conversations that we, as a union - and probably more important as a sport - were showing disrespect for the Maori language."
"Once it was pointed out that there was no 's' in the Maori language, it was a pretty easy decision from a board to make that call."
