"The properties I have sold range from the very modest up to the very substantial.
"There have been a lot of first home buyers and it is always a thrill to help someone purchase their first property."
Bruce McGhie, named seventh on the list, said it was important to build rapport and trust with clients.
"It's about getting yourself out there and building a strong reputation to attract repeat referrals," McGhie said.
"You treat people as you would want to be treated yourself because it can be a stressful experience."
Both agents said they could not have achieved their success without a strong team backing them up and providing expertise.
"We both have partners and my partner Tess Hunt was my personal assistant," Todd said.
"She has so much passion for real estate and is so good with customers, I am delighted to have her as my partner now."
Todd and McGhie said it had been "incredible" to see the growth in demand for Whanganui properties.
"We are seeing people coming not only from Auckland, but from locations like Tauranga and Kapiti," Todd said.
"Although prices have increased here, houses are still more affordable here - especially for first home buyers."
The agents said they had also made "Covid-driven" sales, with Whanganui people returning from overseas to buy homes in the region during the past year.
