About Us


BOP Gear Cutters 1996 Ltd was originally setup and managed by Tom McCulley,
at 28 Triton Avenue, Mt Maunganui, for WM Ross Engineering, a Kawerau based company involved in medium to heavy engineering and Hayes International, a Rotorua based company involved in the building of machinery for roll forming steel sections etc.


After the unfortunate death of Tom in 1998, Hayes International decided to sell

their interests in the company to WM Ross Engineering, who installed Bill Ross as Managing Director. Over a period of some years the company has outgrown its original premises and we have moved to our new location, 33 Aviation Avenue,

Mt Maunganui, a purpose built modern unit which will give the company the room

it needs to grow.


From our original roots we have specialised in cutting Gears, splines and all
of the areas of work involved with it, we have developed a Flame Hardening machine

to harden gear teeth in house, we have added C.N.C. Turning and Milling and offer

an enviable range of services.


We are a small company but, probably one of the best equiped specialist machine shops in New Zealand. Our staff are all skilled, qualified and experienced, and pride themselves in a job well done, paying attention to detail and giving our customers
the very best of service from start to finish.
