Extra staff had been rostered to help cope with the demand.
Bayfair Doctors was open to walk-in patients, which Ms Wilkin said contributed to the spike in patients.
"I think a lot of the patients can't get into their own GPs as well so we deal with a bit of that overflow." This winter's cold and flu season appeared to be worse than last year, she said.
Staff at the practice had also been unwell.
Hospitality student Alexa Halvorsen has spent the past month battling a winter illness.
"At first, I just had the sniffles and sneezing but I didn't really feel sick at all," she said.
"Then I woke up the next day and it felt all in my head, like a head cold.
"I thought I've just got the yearly cold and in a couple of days I'd be right. But I'm not."
Ms Halvorsen is now on antibiotics for bronchitis.
"It became pretty nasty.
"I went to the doctor and received antibiotics. I've been taking those for the past week now.
"I did get a bit better initially but it's in my chest now."
Ms Halvorsen said she had no idea where she had caught the bug from but there were "definitely" more people suffering from cold and flu-like symptoms this winter.
"Pretty much everyone I know has had it to some degree," she said.
Tauranga Hospital emergency medicine specialist Crispin Porter said they had seen an increase in the number of influenza cases in the emergency department during the past month.
"But nothing above what we would expect.
"The numbers currently being seen are appropriate for the time of year."
