The comprehensive breakdown of how the Proteas aim to bowl to the New Zealand batsmen has found its way on to social media as the two teams get set to start their one-day series at Centurion in South Africa.

A hotel guest, who wishes to remain anonymous, posted a picture of the document on Facebook after finding it under her door.

She wrote: "Something tells me I wasn't supposed to get the South African cricket teams plan/strategy for the New Zealand team batsmen and bowlers ... I wonder if this means Dale [Steyn] thinks he's sleeping in my room tonight?"

The plans involve "areas to bowl", how batsmen cope with bouncers, and tactics for each batsmen if they are at the crease during the "death overs".

The document shows the measures the Proteas are allegedly taking to counter Martin Guptill whose strong Cricket World Cup form has continued at the top of the New Zealand order.

Bowlers are advised to go down the line of "4th stump good length – shaping in LBW/bowled. Cuts in the air square on offside. Point square".

Bowling bouncers at Guptill is seen as a "wicket option for bouncers angling in" and the strategy for the opener in the final overs is "yorkers angling in and bouncers in to the body".

Skipper Kane Williamson, who is also in fine form with the bat, is seen as someone who "drives on the up through covers" and "doesn't pull well".

Tom Latham is apparently "susceptible for bouncers angling into the body".

Bouncers are a "dot ball option" against Grant Elliott who broke South African hearts during the World Cup with his six off the second to last ball to win New Zealand the semifinal at Eden Park.

If the South African bowlers face Elliott again at the death they are advised to bowl "yorkers angling in or wide slower deliveries".

Big-hitting wicketkeeper Luke Ronchi can expect some short deliveries as the Proteas view him as a "compulsive puller/hooker" with the bouncer deliver a "wicket-taking option". Apparently Ronchi "gets caught at 3rd man plenty of times".

Colin Munro is viewed as a batsman who "doesn't play bouncers well" and the Proteas bowlers have been advised to aim their short deliveries into Munro's rib cage.

There has been no response from South African officials as to the validity of the document or admission that it was placed under the door of the wrong hotel room.

The two teams enter the one-day series on the back of a 1-1 result in the two Twenty20 matches.

This isn't the first time game plans have been slipped under the door of wrong hotel rooms.

In 2000 Australian coach John Buchanan's plans to counter the Black Caps entered the public domain in similar circumstances at a Wellington hotel on their tour of New Zealand.

In 2001 an Australian plan to deal with South African fast bowler Allan Donald was placed under the door of a journalist staying at the team hotel rather than the room of star batsman Ricky Ponting.

And in 2012 Brisbane's Courier-Mail newspaper got hold of the Australian plans on the eve of the Gabba test against South Africa.
