The surprise result of the first round was Martinborough's decisive 36-9 victory over last year's Tui Cup semi-finalists East Coast at Martinborough.
This was expected to be a close-fought affair but, as it happened, Martinborough ran in six tries to zilch and were clearly the better team.
Tim Roberts scored two of the Martinborough tries and others went to Tipine Haira, Jared Hawkins, Max Hornblow and Nathan Hunt. Tipene Haira kicked two conversions and his brother Himiona Haira kicked one conversion.
All of East Coast's points came from the boot of Byron Karaitiana who landed three penalty goals.
