Chris Cairns has been given full disclosure of testimony and those who have testified against him during his latest interview with the Metropolitan Police.
In the briefing, it is expected he will see at least five current or former New Zealand internationals have offered statements to investigators, including testimony from Brendon McCullum and Lou Vincent that has already been widely distributed.
The full disclosure could be an indication Scotland Yard is close to a decision on whether to lay charges although Cairns is understood to have a written guarantee that he will not be detained and is free to return to New Zealand this week.
Cairns has consistently denied any wrongdoing.
The Herald requested comment from Cairns' attorney, Aaron Lloyd - who has represented New Zealand Cricket previously - but he has not returned calls or emails. However, an automatic reply on his email address suggests he will be back at work in New Zealand on Friday.
