"Although this is great news on most levels, the one thing it can lead to is the expectation that annual growth is a given. Unfortunately, it's not."
George says like any investment the value of KiwiSaver can go down as well as up.
But that doesn't mean people should panic.
"The overriding message is don't base your decisions on alarming headlines."
Instead, George says now could be the time for people to review their KiwiSaver scheme and make sure they are in the right fund for the level of risk they want to take on.
"If, like many members, you are in a lower risk fund, your investment is less likely to be affected anyway.
"If you are investing in the higher risk, higher returns end of the spectrum, we would suggest a conversation with a financial adviser may be a good way to determine your position and what you may or may not want to do."
George said people should consider how long they have until retirement and ask themselves how much income they need in retirement.
Some people close to retirement may have other money they plan to use first before tapping into KiwiSaver.
"It is really based on your individual circumstances. Talk to your provider and get targeted personal advice."
George also warned people against stopping their contributions.
"Your retirement goals are more attainable if you continue to contribute regularly."
Those who stopped putting in money risked missing out on the employer contribution if they were employed and the Government's annual KiwiSaver subsidy - the annual member tax credit, he warned.
