South Africa legend Allan Donald believes that New Zealand's bowlers need to up their aggression if they are to turn around their poor run of form in the one-day game.
Donald has been named as the Black Caps' incoming bowling coach and takes the role at something of a lowpoint in their fortunes.
New Zealand have lost 11 straight ODIs as they go into their six-match series against Pakistan - which forms the bulk of their World Cup preparations.
Donald, known as "White Lightning" in his playing days, wants to get the bowling attack firing as soon as possible - and said young paceman Tim Southee has the qualities he is looking for.
"The big thing I always focus on is attitude and intensity and that all starts at the training ground," Donald said.
"I like bowlers with white-line fever.
"(Southee) brings a lot to the table, he just needs to be channelled in the right direction. That aggression is good and that's the kind of attitude I am talking about as a collective unit that we need to instil.
"I know it is not in everybody's culture, and their make-up, to be that aggressive but I think the team needs to understand how it lifts people and the buzz it creates."
