A Hamilton businessman has offered a $1000 reward to help catch the burglars of Chiefs coach Dave Rennie's house as his team won the Super 15 final on Saturday night.

There have been messages of support from all over the world for Rennie, who said the anonymous reward was "pretty neat".

The burglars stole a safe containing his wife Stephanie's jewellery.

"My wife is really upset. We've been together almost 30 years so there's lots of anniversary presents which are irreplaceable.


"There's a necklace in there that my father bought for Steph. He died quite a few years ago now so that's got strong sentimental value."

Rennie believed the Hamilton house, which he and his wife bought in February, was targeted by professionals who knew the family would be at the game. He said Sonny Bill Williams' home was burgled a couple of months ago during a Chiefs game, "so it's a hell of a coincidence, isn't it?"

He said the thieves used a crowbar to get in and take the safe, which was hidden and bolted to the floor. It also held foreign currency and son Matthew's university graduation certificate. The offenders also took a laptop.

Rennie said all the couple wanted back was the jewellery. Much of it was distinctive and one-off items made for his wife.

The couple had beefed up security at the house, including fitting an alarm sensor in the master bedroom and extra spotlights.
