Nearly two thirds, 60 percent, have an emergency plan and 92 percent have survival items.
The proportion of residents from the Bay of Plenty that have seen, heard, or read advertising about preparing for a disaster is generally consistent with the national average.
Residents who have seen the Get Ready Get Thru television advertising are significantly more likely than average to say that the advertisement prompted them to visit other disaster preparation websites.
"We'd like to see more people being better prepared as that will mean fewer people needing emergency services help when they could help themselves," Mr Naude said.
"A lot of people are partially prepared, or know what to do, but haven't made the move to being fully prepared."
Being fully prepared means having an emergency kit containing food, water, a radio, batteries and a torch, having at least three litres of water for each household member, and having a family or household emergency plan.
"We'd really like people to take action now to ensure their family and friends are protected and prepared in an emergency and won't need emergency services help.
"Check with your neighbours, friends and family now. Have a chat about what survival items you can get together now, and what you'd do and where you'd meet in an emergency."
The Ministry of Civil Defence and Emergency Management has carried out the survey of emergency preparedness annually since 2006.
