The eruptions were happening directly in front of the channel which should run into Ruapeka lagoon, Ms Kereopa said.
The lagoon had been closed off from the lake as a sandbar was developing in front of it.
She said she could not help but feel it was connected as there had been no eruptions before it closed itself off.
Since the lagoon was cut off it was getting hotter and Ms Kereopa said she thought it would be worth opening the channel again, to see if it had anything to do with the eruptions.
Rotorua Lakes Council held a recourse consent to dredge the lagoon from 1998 to 2013, but had not since renewed its consent.
GNS Science volcano information specialist Brad Scott told the Rotorua Daily Post the area around the lagoon had been modified in the last decade or so "with land reclamation, dredging and general earthworks".
"But the main vent is not in that area and is in the main body of the lake.
"I don't think there is any connection to that and the eruptions."
He said scientists would be back at some stage to check the area again.
A Rotorua Lakes Council communications spokeswoman said council staff did not have the scientific knowledge to comment about the lagoon or the cause of the eruptions.
However council sport and recreation Manager Rob Pitkethley said he was unaware of any approach to the council regarding dredging of the lagoon at Ohinemutu but he would be happy to speak with the Ohinemutu community about it.
