New Zealand Cricket has promised heightened security during the one-day series after the Indian camp protested against the incident.

As a precautionary measure, the first three rows of the stadium here would be kept empty to create a buffer-zone between spectators and players during the second ODI on Friday.

Grey said though the bottle landed close to a player on the boundary during Sunday's match, which the hosts won, it wasn't a major incident.

"It wasn't a major (incident) and there's a little bit of doubt as to whether it was actually thrown at the player," Gray was quoted as saying by 'The Dominion Post'.

"It was an incredibly well-behaved game. I talked to the police afterwards and they were totally happy," Grey added.

Grey said compared to what has happened on Indian grounds in the past, the incident can hardly be called a security scare but he could understand the visiting players' concerns as they were new to the country.

"I think it was pretty justifiable. They had their backs to the crowd, they've not been here before and they don't know what's going on," he said.
