Others in the Tech performance were the four-try bag for the wings, with two to Ben Lewis, and one each to Bethel Malasia and substitute Cruz Davies. Sheridan Rangihuna converted six of the seven tries.
The feature for Pirate was the brave second-half effort, down to 14 players with a red card to long-serving prop Sean Morrison and after Tech led 35-7 at the break.
Tech manager Cyril Whitburn said the side had a good start with numbers at training, having overcome a Covid issue which threatened the side at the time the competition was to have started in March and a suitable schedule, giving time to develop the side.
It has an away match against Clive next Saturday, while Taradale will be at home against MAC.
In other grades, combined side Tara/Tech sealed women's grade honours with only a bye remaining, beating Hastings R&S 43-5 and being presented on the day with the Big Marsh Cup. Clive won the Colts' first-round final for the Arthur Brown Cup with a 38-0 win, also over Hastings R&S.
In Senior 2 rugby Bridge Pa continued an unlikely run for glory in just its fourth season in the Senior grades, making it four-from-four with a 65-12 win over Napier Pirate at Mitre 10 Regional Sports Park, Hastings. It's the type of form which could see the club in Premier rugby next season.
