Mr Howard spoke to the Wairarapa Times-Age after a Canster Blue nationwide survey revealed almost half of New Zealanders were living day-to-day without a nest egg or savings.
The company interviewed 2240 people, including people in Wairarapa and 44 per cent of respondents said they were living pay day to pay day.
Mr Howard said he was not surprised by the results of the survey but said it was important for people to have some savings put aside in case of an emergency.
He said it was also important to shop carefully. "It can be difficult for some people. It's very important you have some savings," he said.

"Winter is coming as well and the cost of higher heating costs will make it much more expensive for people and will continue to impact on families surviving."
Mrs Potts said it took courage for people under financial pressure to contact Masterton Food Bank.
"It's very stressful. It's difficult for people to approach the food bank and when they do we see that stress."
