Former Australian captain Ricky Ponting took the stand on Tuesday via video link.

Ricky Ponting was with Brendon McCullum in a Kolkata hotel in 2008 when the Kiwi got a phone call from "Cairnsy", the former Australian cricket captain has told London's Chris Cairns perjury trial.

McCullum told him the short call related to "business", so he asked no questions about it, Ponting said.

"He put the phone down, hung up and said 'that was Cairnsy, he just made me a business proposition'," Ponting told Southwark Crown Court by video link.

They did not discuss the details.

"As soon as I heard it was about business, I wasn't interested any more."

The pair parted and went to their rooms soon after. Ponting recalled the call coming during daylight hours.

At the time, McCullum was his Kolkata Knight Riders team-mate in the Indian Premier League (IPL), while former outstanding all-rounder Cairns was captain of the Chandigarh Lions in the unsanctioned Indian Cricket League (ICL).

In evidence last week, McCullum said Cairns sent him a car which took him to his hotel, where he alleged spot fixing was discussed.

McCullum and Cairns they shared a bottle of red wine, then ordered a curry, after which Cairns asked him whether he knew how to spot fix a game.

When McCullum said no, Cairns produced a pen and paper and explained the principles.

To the jury, McCullum summed fixing up as to "under-perform" in brackets of overs, by batting poorly.

McCullum was a wicketkeeper and opening bat with the Knight Riders.

Cairns offered him up to US$180,000 to participate in spotfixing, the jury was told.

McCullum said he declined the offer soon after and also rebuffed a second approach, in England.

He did not tell Ponting what he said happened at the meeting in Kolkata.

Cairns, 45, is charged with perjury for allegedly lying under oath in a libel trial, saying he'd "never" cheated at cricket.

A former Wisden Player of the Year, he has denied the charges. The maximum sentence for perjury is seven years' jail.

Black Caps Shane Bond, Andre Adams and Kyle Mills also appeared by video link last week; Bond from the US, Adams and Mills from New Zealand.

Ponting, whose nickname is Punter, was asked by defence lawyer Orlando Pownall, QC, whether he considered McCullum knew about match fixing, and would have needed it explained to him.

"Right now, I would. In 2008, not so much."

A call about a business proposition "was wholly unremarkable, was it not?" Pownall said.

Ponting agreed.

Nor had he discussed the call with McCullum during the IPL, even though they spent time together, or since.

"For a start, I wasn't aware Brendon had gone and spoken to Chris Cairns," he told the court.

Pownall asked if that was unusual.

"It was none of my business. Brendon's private life and business life was none of my business, I wasn't going to ask him."

Ponting said match fixing was talked about by players in general terms, rather than specifics. He had not paid much attention as he wasn't interested.

He did not know McCullum well enough to say what his relationship with Cairns was in 2008.

Leanne McGoldrick, agent for several Kiwi players in the ICL and McCullum, took the witness box after Ponting's face disappeared from the court room television.

She outlined an evening when her then-client McCullum asked her whether she thought Cairns was involved in match fixing.

It was at a dinner in her Christchurch home, after the 2008 New Zealand cricket tour of England. In was on that tour, Cairns and McCullum met in a Worcester cafe for breakfast.

McCullum alleged it was there Cairns made a second approach to him to spot fix, he told the court last week.

McGoldrick said McCullum had first asked if she thought any New Zealand players were match fixing.

When she said she didn't think so, he asked about Cairns.

"I said I didn't think he was," McGoldrick told the court.

"He said he'd had an occasion in England - in a bar or cafe, I can't remember which - with Chris, and Chris had asked him whether he knew how to spot fix."

Cairns had allegedly told McCullum "it was very easy to manipulate, and it was easy to do", she said.

"I was completely shocked ... I couldn't believe what he was saying."

When she asked McCullum if he could have been mistaken, he told her "no, he hadn't". She told him to report the approach to authorities.

He said he would, but their business relationship ended soon after and she did not check if he had.

As well as Ponting and McGoldrick, the court heard from New Zealand Cricket (NZC) chief executive David White, International Cricket Council (ICC) anti-corruption investigator John Rhodes, and English club cricketer Phill Hayes.

Hayes befriended now-banned Kiwi cricketer Lou Vincent when he played for the Ramsbottom club, between two 2008 stints with the Chandigarh Lions.

Vincent gave him tickets to go to cricket matches, he worked around the cricketer's house and at times baby sat for him and his ex-wife, Elly Riley.

Once, he went on a run to Birmingham to pick up cash Vincent was being paid for match fixing, although he didn't know that at the time.

He wound sitting in an Indian restaurant in a poorer part of town, while Vincent was out the back.

At his engagement party on October 10, 2009 Vincent turned up on his own and agitated.

"His mood concerned me enough to leave the party," Hayes said Vincent told him his marriage was in trouble.

Months later, after Vincent had been kicked out of home, they went drinking together, with Vincent telling a stunned Hayes he had been involved in match fixing at the ICL.

"He said everyone in the ICL was involved in match fixing - he said Chris Cairns was the ring leader. Daryl Tuffey is another name he mentioned," Hayes told the jury.

Of the three Kiwis, Cairns was Chandigarh captain, Vincent opening bat, and Tuffey a fast bowler.

Vincent talked of the time when he had "messed up" a fix by hitting boundaries, when he was meant to get out, and Cairns threatened him with a bat, Hayes told the court.

"The mood of the evening was him telling me everything that had gone wrong in his life."

At the time Vincent - who claimed Cairns introduced him to match fixing in India - was working as a tiler without any prospect of making money from cricket.

Hayes said it was a big surprise to later learn that Vincent had fixed English county matches.

"I'd invested so much emotional energy in wanting him to do well."
