It's official - All Black legend Richie McCaw is off the market.

He's married Gemma Flynn at a ceremony in Wanaka.

Guests started arriving at the venue the Olive Grove as early as 1pm, and about an hour later two Mercedes Benz believed to be carrying the bridal party rolled up.

There's been a high security presence at the wedding, which is believed to be because an exclusive magazine deal is in place.

Security firm Platform4 Group said it was providing security for the wedding on private property

Notable omissions from this afternoon's proceedings are McCaw’s long time All Black team-mates, and great mates off the field, Ali Williams and Dan Carter.

Both are in France with their club Racing 92 ahead of this weekend’s European Champions Cup clash with Leicester.
