The New-Zealand born powerhouse is to make his GUINNESS PRO12 debut at outside centre against Edinburgh, having joined up with the squad from rugby league's South Sydney Rabbitohs earlier this month.
As such there's been little time for the 27-year-old to bed in at the Irish province, though he's been helped along the way by two new housemates in Rob and Dave Kearney.
But O'Connor says Te'o has swatted up on his new code well ahead of time - and will only get better from here on in.
"He's a little bit down on the nuances of the game but he's an incredibly fast learner and the more he plays, the better he'll be," said O'Connor.
"He's a very powerful defender, carries the ball incredibly well and we'll be looking to get him involved in those aspects of the game as often as we can.
"The reality is you've got to look at as much rugby union as you can. You've got to immerse yourself in it and thankfully he's been living with Rob and Dave Kearney and we'll certainly be using every avenue we can to expose him to the game, and look at the game."
