The town has tertiary institution Te Wananga O Raukawa, as well as two Maori immersion schools and two bilingual units in mainstream schools.
Kapiti Coast District Council has said the idea has potential.
Mayor K Gurunathan said it was a good opportunity to stand out.
"From where we sit, I think it's a good opportunity. One only has to think of the expressway coming through ... we need points of difference. We need to be unique," he told Fairfax.
Maori Party co-leader Te Ururoa Flavell said discussions had been held with Otaki and Rotorua about becoming bilingual, and Wairoa also had a similar goal.
"There is potential to partner with Government, local government, community and Maori to trial a bilingual approach.
"We'd love for more communities and towns to become bilingual and believe Otaki, and perhaps Rotorua and Wairoa, could become the catalyst for others to follow suit."
