Noon today passed without any significant incidents in Auckland or Wellington, Assistant Commissioner Jon White, said today.
"A number of phone calls were received purporting to be bomb warnings in Wellington and Auckland but all proved to be false alarms and it is not believed that any were related to the recent terrorist threats.
"In Auckland the New Zealand Herald received two letters. The letters were similar in tone and style to previous letters. The contents are being analysed but cyanide was present.
"I can indicate that the wording reaffirms threats made against US, British and Australian interests in New Zealand.
"Without further analysis, Police are reluctant to reveal further details. The letter does, however, make threats against food and drink products.
"Police would remind the public of earlier advice concerning the need to remain vigilant, report any suspicious activity and check food and beverage sources.
"Nevertheless, Police advice is that people should continue to go about their normal business. If they do see anything suspicious, call 111 or if they have information of interest to the investigation team then call 0800THREAT (0800 847328) or email www.police.govt.nz," said Assistant Commissioner White.
