The trip comes after months of protests in opposition of Norwegian oil company Statoil exploring for oil and gas in Te Reinga Basin.
Ms Maako said the group would take letters of opposition on behalf of Ngati Kuri, Ngati Kahu and Te Rarawa, which had also been passed on to Prime Minister John Key and Simon Bridges.
"Te Hiku holds significance for Maori and the rest of New Zealand. Many people, including foreign tourists and New Zealanders, pilgrimage to see the two oceans meet at Te Rerenga Wairua [Cape Reinga]," she said.
Ms Maako said the need for oil exploration in the basin was unnecessary.
"The ultra Deep Sea Oil exploration projects are extremely risky and we don't need more fossil fuels, we have enough. The real threat is any oil spill will be a thousand times worse than what we have seen in Tauranga. We don't have the resources here to deal with such spill like in the Gulf of Mexico."
The trio will also meet with a range of other groups to spread their message.
"We're also meeting with civil society groups, NGOs, uni students and environmental groups to ... let them know what this means to the indigenous people of Te Hiku."
