We have been clients of JB Motors from the inception of their business. They have worked on both our business and private vehicles. Where they are able, they will find second hand parts to use to keep costs down. They only do work that is necessary and always advise what may need doing in the future. Their workmanship is of a high quality as was remarked upon by a mechanic when our vehicle was sold. We have always found Matt and James to be courteous, honest, helpful and professional in our dealings with them and we recommend others to use their services.



Having recently moved into Mangawhai we needed somewhere we could rely on to look after both mine and my wife’s vehicle. We did the obvious thing and asked the locals. Taking on board their advice we have not been disappointed. The service at Jackson Brown Auto & Marine has been excellent… on time, schedule of billing and explanation of work done, great service reception and all in all a credit to Kiwi small businesses. Well done guys!


“JB and the Team have been servicing my power boat and vehicles for past four years, since we purchased in Mangawhai. The service and attention to detail is excellent, the team always check everything fully. Many a time, they have fixed and addressed issues before I have noticed them. JB’s always pick up and drop off which is a great service for me as my time at the beach is spent doing the things I want like more fishing! The pricing and quality of work is far better than I have experienced in Auckland. Thanks JB look forward to your continued service.”

Hello J B Team. I’ve experienced great service from your team on my Kawasaki Jetski, Haines Hunter with Yamaha 115 motor, 20 year old Boat, trailer maintenance, beach tractor repairs, WOF etc, nothing is a problem. The toys must be maintained to be reliable just not getting enough use!!

Jackson Brown has serviced the 90 horsepower Mariner engine on my boat on several occasions. The engine seems to be better tuned than at any other time since I purchased it. Last year, we decided to upgrade our boat instead of purchasing a new one. I approached Jackson Brown to discuss the feasibly of fitting an automatic anchor system to the craft and to upgrade the electrical system. A plan was presented to me and following this, a Maxwell Anchor Winch was installed and a second battery fitted. The workmanship is outstanding, the work was carried out on schedule and communications from the firm were excellent. I believe that Mangawhai boat owners are fortunate in having a reliable and experienced company available to service their craft and have no hesitation in recommending Jackson Brown.

Hi Matt and James, I just wanted to thank you both for the help you’ve given me. You did a great job with the re-power with the new/second-hand motor on my boat in 2011, and I’m really impressed with the way you tidied up and modernised the dash area to take the new instruments. When the new (second hand) motor played up over Christmas this year, I really appreciated the way you got the parts in so quickly and squeezed me in, so that I could be back on the water so quickly – you saved our holiday! Your service was exactly as it has been consistently over the years – fantastic! I particularly appreciate your willingness to pick my boat up and drop it back to my place, that was a great help. Thanks guys, I’ll see you again when the boat or trailer or my 4wd is next due for a wof or service or whatever comes first! Cheers
