Morrinsville's mega Fresian in all its bovine glory.

As fog lifted in Morrinsville on a typical Waikato winter's day, the Morrinsville Mega Cow was finally unveiled for all to see.

Hundreds of people lined the main road into Morrinsville outside Maber Motors Power Farming to get a first glimpse of the Morrinsville Mega Cow.

Laurie and Yvonne Maber's grandson Brett Maber oversaw the project and said his "Pop" wouldn't have needed his signature specs to see the 6.5m beauty.

"Today is a pretty special day for the Maber family and the Morrinsville community," he said.

Geoff Maber said cows were his father Laurie's life.

"He made a successful business out of cows and the farming industry with Maber Motors started in 1946," Geoff said.

"What a lot of people don't know is that he also built the first rotary shed in the area many years ago."

Forty years ago, Laurie who was Morrinsville's mayor at the time, suggested a large cow be built to acknowledge the town's thriving dairy farming industry.

However, according to Laurie, "those were the hard days when making money wasn't easy", and his idea got put on the backburner.

In recent years, Laurie was so impressed by the Herd of Cows? street art project, headed by Morrinsville's Nicki Robb, that he suggested his 40-year-old idea to his family.

"My dad was the type of man who wanted things done yesterday," he said.

"He was 95 and said "let's get going with this giant cow, I'll fund it but if I die before it's finished you can pay for the rest".

It took Mat Bailey and his Matcraft Industries team 18 months to get the Mega Cow finished and Geoff said there were times when they thought it might not become a reality.

"Pop would be over the moon," he said

"Whereever he is, he'll be smiling down on us thinking 'S**t, that's pretty bloody good'," Geoff said

The massive bovine, affectionately known as the mama cow, has now joined the Herd of Cows? project, which now has a total of 42 colourful, life-sized cows.
