The 24-year-old forward will arrive in Scotland next week, fresh from helping the Dunedin-based outfit to five wins in the ITM Cup (previously the NPC and Air New Zealand Cup).
Verbakel holds a Dutch passport, with both of his parents having been born in the Netherlands. He came to rugby relatively late, only beginning to play the game seriously while he was at university in Christchurch.
His progress was instant and impressive enough to win him a place in the Canterbury ITM Cup side last season, before he earned a move to Otago for the 2011 campaign. Verbakel scored his first ITM Cup try in their opening match of the season, against North Harbour.
The Nelson-born second row, whose family are farmers and who holds a degree in civil engineering, today told www.glasgowwarriors.org of his excitement at the prospect of joining the club.
He said: "It's a fantastic opportunity for me to be coming to a side who play in two of the best club competitions in the northern hemisphere, the RaboDirect PRO12 and Heineken Cup.
"I was thrilled to get the call, and it wasn't something I needed to think particularly long about. I know I'll be arriving with the season already underway, but I feel like I'll be showing up battle-hardened after my involvement with Otago and my aim will be to hit the ground running with the Warriors.
"The talk back home is all about the Rugby World Cup, and it's obvious from the number of guys Glasgow have involved that I'm coming to a quality outfit. It will be great to learn from these players, and hopefully bring the benefit of my own experiences as well.
"I appreciate the efforts of everyone involved in putting this together, especially Glasgow Warriors and Otago Rugby Union"
Warriors head coach Sean Lineen today hailed Verbakel's addition, confirming to www.glasgowwarriors.org: "I'm very pleased to have Rob signed up, both because he's a player who will bring a number of very positive aspects to the group and because of the timing.
"We're delighted to have given so many players to the Scotland squad, but it's also good to have a bit more depth in our squad and I'm looking forward to seeing Rob challenge the likes of Tom Ryder, Rob Harley, James Eddie and Nick Campbell for a place in the second row.
"He's a powerful kind of lock, whose basics in the set-piece are very strong and who likes to carry the ball. I'm very confident he will be an asset to the group in what is a vital stage of our season."
