Why Use a Broker?
"It's about getting clients the right result. Everyone can buy a policy online now, of course, but 99% of the time they're not going to have the right cover." - Grant Maddison
Navigating the hundreds of different insurance and investment products available in 2021 to find the best deals, cover and returns is a complex task.
While it's tempting to dive in and find the solutions online yourself, Grant says that is the equivalent of having a sore tooth and, rather than going to see the dentist, heading to your garage to find a pair of pliers.
Similarly, banks and individual companies are focused on selling their own products.
A broker provides access to the whole market and can provide a bespoke package of products, handpicked to suit your business or home life.
Tailored financial advice will ensure you are not missing opportunities to make the most of your capital or KiwiSaver.
Personal contact throughout is another major benefit. "I pride myself on dealing with the claims - the whole process, rather than just selling a policy. I want to make the process as easy as possible for them when things aren't good."
