The work that still needed to be done included completing the new sewer and water pipes in Te Mata Rd and St Hill Lane, and the associated sewer chambers at intersections along Te Mata Rd, between Durham Drive and St Hill Lane.
For motorists this would see sections of St Hill Lane closed to traffic (except for residents, their visitors and service vehicles) in stages while work was completed.
Parts of Te Mata Rd would be reduced to single lane for periods during the day.
"Temporary traffic and pedestrian management will continue for the remainder of the project to ensure the safety of road users.
"Some delays should be expected and alternative routes used where possible," the spokesperson said.
Nearby residents and businesses affected by the works would be updated on progress individually.
She said the council's contracts all included a contingency to cover unforeseen circumstances and other valid variations, and the project remained within budget.
Meanwhile, local businesses are up in arms over the news that work will continue for another three months, claiming they hadn't been updated.
Village Kids Childcare centre at 144 Te Mata Rd has felt the affects of the continued work.
Owner, Paul Rooney said "it has affected my business not in revenue or downturn, but rather it has been a huge inconvenience for dropping off and picking up children from our services".
For some time they had their entrance blocked due to the work and although it isn't any more, Mr Rooney noted that there have been parents complaining that they can't turn easily.
He hadn't heard anything about it taking longer and is concerned given that when school starts, he will be bringing 40 students from Te Mata School along the road to the child care facility.
Similarly, Smile Haus Dental co-owner Rachel Perrott hadn't heard about the latest development and believes April is a "long time" for it to carry on until.
"It has at times been very difficult for our patients to access our business and there have been a lot of dangerous situations for people on bikes and mobility scooters and when people are turning or getting out."
"We are all about giving patients a very zen experience and we go to great lengths to make sure it is a very calm and inviting experience and to hear a jackhammer going in the background is a little unnerving for patients," Mrs Perrott said.
A Te Mata Rd resident who did not wish to be named said it was a "very sore topic" but it was something that had to be done.
"It is very frustrating. You have to plan your route more carefully and you can't turn on to any of the side roads. I hope they do it once and properly."
She hadn't been updated either.
