The organisers of the crowdfunding campaign went into "stealth mode" last week to prevent opposing bidders from knowing exactly how much money has been raised.
In the face of criticism by millionaire Gareth Morgan, who described their campaign as "naive", the Givealittle organisers consulted lawyers on Friday and discovered they were able to freeze the published total at $2 million, while keeping the pledges coming in until 3pm today.
Since the $2 million target was reached, only the increase in the number of people making pledges was revealed on the site. The final tally will be kept secret.
