Our teams from Legrand, Trical, and MSS came together at the Trical factory yesterday for the final of our table tennis tournament - a morning of friendly competition and connection.

Each company fielded two pairs, backed by a very vocal group of supporters 👏

Trical came out on top, with Legrand taking second place. The winning shield will now be engraved for 2025 and handed on each year as part of an ongoing tradition 🏆

It was a great way to bring people together, strengthen relationships across the three businesses, and involve whānau too!
