As of this afternoon two deaths have been confirmed but there were still parts of Tonga where communication remained difficult or non-existent.
Heilala Vanilla set up the Heilala Vanilla Foundation as an aid project partnering with the people of Vava'u in 2013. Since Saturday's eruption, it has put $25,000 into the foundation to support the Tongan community.
Boggiss said the company had been "overwhelmed" with support after it launched the appeal for Tonga on Monday night with more than $12,000 donated in less than 24 hours.
"I hope we're in a position to be able to offer some support once we know what's actually required."
She believed the immediate relief would come from the Government and large agencies helping with food and water.
Heilala Vanilla would likely focus on food and water security, she said - things like seedlings and long-life food.
Boggiss said the company was worried about what would happen to the people, communities and their livelihoods following the eruption.

She said it was still unclear what impact this would have on the business but, from a business perspective, the worst-case scenario would be no supply this coming year.

However, there were plantations in multiple areas in Tonga and Boggiss said it was unlikely they would all be impacted and the company also had supply partners in other countries.
There were more than 20 people on the team in Tonga who worked with more than 300 vanilla farmers, she said.
Boggiss said she understood the places the company had a home — Vava'u and 'Eua — were not badly impacted, but it was unclear what happened on the surrounding smaller islands.
"We have really close ties particularly with a couple of communities on Vava'u where we have a home. They're like family," she said.
Boggiss said from a business perspective, it was lucky the annual crop had already been harvested and the plants were "hardy".
However, it was unclear what ash did to the plant health and the company was working with Plant and Food Research which was liaising with volcanologists, researching the impact of ash on plants.
Another aspect would also be how much the saltwater spray affected crops.

"It won't just be vanilla that's impacted, it's people's food security, and that's the biggest concern."
Boggiss said her team knew many of the growers and exporters and "we really feel for them".
"We will absolutely not move somewhere else, we're committed to Tonga."
Katikati's Simione Vakasiuola just wanted to hear his families voices again.
He's lived in New Zealand with his immediate family since 1993 and his extended family still live in Tonga however, he said his family lived on higher ground and he believed they were safe.
"It's the unknown; the uncertainty that's hurting us.
"We know that they are fine, but that's not enough - we want to hear their voices. Hearing their voices would be comfort for us and we'll know they're really okay."
Like other families in New Zealand, he hadn't heard from loved ones since the eruption.
