Sonny Bill Williams will have no hesitation in answering an SOS call from Steve Hansen to put on the black jersey for two more tests.

With Conrad Smith out for the first part of the Rugby Championships because of the need to have eye surgery and Richard Kahui not available until next year due to a shoulder operation, the All Blacks selectors have been left with few options for the midfield in the upcoming two Bledisloe Cup tests, in Sydney and Auckland.

As Williams is off to Japan later in the year and then heading back to the NRL, he would normally no longer be considered for the All Blacks.

But NZRU CEO Steve Tew opened the door for a recall last Thursday by stating that he was still available for selection and yesterday All Blacks coach Steve Hansen confirmed that they'd be looking for Williams to help them out of a fix.

Speaking on the issue for the first time today, Williams said he's delighted to be able to represent his country for a bit longer.

"I just had a quick chat with Steve and he told me about their situation," Williams said after a Chiefs training session.

"I said, of course I'd love to [play] if all the things are right on the Japanese front and it's worked out well.

"But that's probably the only time I've talked about it.

"You guys [the media] have made a big deal about it, but for me, my heart, soul and mind is definitely with the Chiefs.

"One more week and then I'll worry about that."

The question ahead for Hansen and the other All Blacks coaches is which way round to have Williams and Ma'a Nonu as both prefer playing second-five to centre, but one of them will have to move into the No 13 jersey for the tests.

While the national interest is on Williams playing for the All Blacks again, in the Chiefs area all of the focus is on Saturday night's Super Rugby final against the Sharks in Hamilton.

It will be Williams' last appearance for the franchise for the foreseeable future. He has had many huge games over his career and he is placing this one as one of his biggest.

"This is definitely right up there," he said.

"I have played in a lot of teams but I guess the emotions I feel when I'm playing with the boys, especially after last week's win, was probably second to none.

"So hopefully we do win this week and this will definitely be up there."
