Roads closed around the lodge from 2pm ensured that no one could get close enough to take a look, and even neighbours were asked not to allow onlookers on to their properties.
The wedding glamour was briefly on show around 3pm as many of the guests boarded buses with tinted windows in central Blenheim for a 10-minute journey to the lodge.
The men were impeccably dressed in suits and ties, while the women wore a range of brightly coloured dresses, hats and fascinators.
Among those travelling on the buses were World Cup-winning former All Black coach Graham Henry and his wife, Raewyn, and former All Black Leon MacDonald and his wife, Hayley.
All Black captain Richie McCaw, hobbling on crutches after an operation on his foot, went by car from a Blenheim motel to the wedding.
Guests had been mostly unwilling to comment on the wedding after being asked to keep details secret. Honor Dillon's uncle, Richard Dillon, told the Herald that the invitation did not even disclose the venue. He was predicting a "joyous" occasion.
