The 31-year old made his first-class debut for Otago in February 2001 and played 43 first-class matches before transferring to Northern Districts in 2008.
He made a promise to Otago medium-pacer and good friend Warren McSkimming that he would return and delivered on that pledge yesterday.
"I made Warren a promise years ago and I sent him a text in Scotland saying it would be good to get the old firm back together again," Scott said.
The pair formed a great partnership over seven seasons and grew up playing alongside and against each other at age-group and club level.
The decision to shift to Hamilton three years ago was a tough call for the proud Otago man.
But his wife, Jennie, had a teaching job in the city and Scott thought it was time to put family first.
But with the arrival of the couple's second child, Lucie, on June 30, Scott said it felt like the right time to return home. He also felt his cricket career would be better served by the move south.
"There has always been the lure of family and that support structure with both our families down there," Scott said.
"But I could list several reasons. That is why it was such a difficult decision because there are pros and cons in both places.
"But my first-class statistics for ND don't make great reading and I think I still have something to offer in the four-day version of the game," Scott said.
Scott has an impressive record for Otago, capturing 142 wickets at an average of 25. He did not have the same success at Northern Districts with 21 wickets at 52.23 in 16 games.
Otago coach Vaughn Johnson welcomed news of Scott's return.
"He will add some depth to our seam attack, obviously," Johnson said.
"But one of his main attributes is he has proven over the years that he does not get injured a lot.
His reliability is huge for us."
Competition for places in the starting XI will be fierce. The likes of Neil Wagner, McSkimming, Ian Butler, James McMillan, Anthony Bullick and Craig Smith will all compete for three or four spots.
Scott is teaching at Hamilton Boys' High School and will return to Dunedin in October. He will play for his beloved club Green Island and look to stake his claim at club level and in trial games.
Northern Districts Cricket chief executive David Cooper said Scott's absence would be felt both on and off the field.
"Bradley has always gone the extra mile with partners of our organisation and is a naturally friendly and engaging person, so his easy-going nature made him an integral part of the team," Cooper said in a press release.
"His skills will be missed, but we wish Bradley and his family well as they head home for the coming season."
