"People are shocked when they find out he only has a week left, they don't know how we can be so happy and strong. It's because right at this point we still have Troy so we need to be grateful, happy and enjoy it. A time will come when we are sad and it will be for a reason."
Ms McVeigh said Troy noticed lumps on his groin lymph node area last year.
"We thought his body was fighting an infection, it wasn't until they did not go did we start to worry. On the 9th July, 2014 his doctor confirmed it was cancer."
While the whole family was shocked by the news, Troy used the last eight months to write a bucket list and he, his family, friends and the wider community have done everything in their power to make his wishes come true.
Included in the list was to own a rotary car and have a 13b turbo engine for it. He checked these two wishes off his list when he got his Mazda RX7 with the roaring engine to match.
He was also able to fly in a glider and even take a joyride in a Ferrari earlier this week.
Ms McVeigh said her little brother had always had a huge interest in cars and remembers him playing with toy cars as a kid, "vroom, vrooming" them across the carpet.
"Even when he was a toddler he would put his head on the carpet and drive toy cars around making noises, we used to make dirt tracks and push them all around. We had a paddock basher too and his friends would come around and they would hoon around in that.
"We also used to have this little scooter, it was a real little piece of crap, but I would sit on the back where you have your groceries and we would hoon up and down the road on it."
The 30 cars he had owned were testament to his hard work and determination.
"At one point he had four at once. We would joke about 'his car sales yard' but Troy is so kind and caring too, he's not judgmental, anyone can chat with him and feel comfortable.
"He's honest, has tact and a real go-getter, if he wants something he would work towards it."
Troy grew up in Pongakawa, went to Pongakawa School and Intermediate and on to Te Puke High School.
However, he left school when he was 15 and went straight into diary farming.
"He really enjoyed coming out of school at a young age and getting straight into work and he's done well. How else was he going to be able to afford the car he wanted?"
Ms McVeigh said she and her family wanted to thank all those that had made Troy's dreams come true over the last several months.
"From our family through to partners and their families. Friends, all of our friends we are close with and the friends whom we only talk with once a year. All offering emotional support, cooking, cleaning, caring, pick ups and drop offs.
"From Canteen to Waipuna Hospice and The Green Brothers making all of Troy's rotary dreams come true, from the car to the engine to the wheels, with hours and hours of work. Everyone who has donated or sent words of kindness and support. Everything has meant a lot to our family and is and has been hugely appreciated," she said.
Last Thursday doctors gave Troy just two more weeks to live.
"He is very sick. It's at the point now, he was given two weeks. But at the same time he's not really taking it lying down.
"He's using the small amount of time he has got left [to keep doing the things he loves].
