The 58-year-old Smith, a hugely respected figure around the rugby world, opted not to comment when approached by Radio Sport, which will only fuel speculation that he is about to depart for the big English club.
With two World Cups under the belt as a highly influential assistant to Graham Henry and Steve Hansen, Smith is an obvious target for some of the world's biggest rugby clubs.
"No comment really," he told Radio Sport.
"I'm considering several options regarding my coaching future, whilst also trying to have a short break from the game. I'm a wee way from making any decisions."
Smith's words will only fuel speculation that he is about to head offshore, with Harlequins firming as favourites for his services.
British media reported that he is in talks with the club, whose current coach Conor O'Shea will leave at the end of this season. The Times reported that Harlequins players were excited at the prospect of Smith's arrival.
Smith, who initially made his coaching name taking the Crusaders to their first two titles, had instant success at the Chiefs assisting Dave Rennie, as the franchise became double Super Rugby champions under their leadership.
He was the All Blacks head coach in 2000/01, and coached Northampton for three seasons.
Smith has built a reputation as a clever and tireless coach who gets the best out of players because of a selfless and genuine nature, along with having the keys to the vault holding New Zealand's best rugby knowledge.
