Packed buses and stalled highways are already upon Auckland, and it is not even March yet.
The peak month for Auckland transport is March, known as March Madness, as about 100,000 university students join the city's commute.
This year many of those students are returning a week early, as the University of Auckland and Auckland University of Technology start on February 26, and have orientation weeks on February 19.
The month is also filled with popular events, including the Lantern Festival, Pasifika, Super Rugby, the Auckland Arts Festival and Polyfest.
Since last year Auckland Transport has improved bus networks east and west of the city, and are adding 4600 spaces on the northern bus routes through March to cope with the increased demand.
There will be 99 double deckers operating on various routes, as part of the 1300-strong fleet, to help meet demand.
No double decker buses operated in Auckland a few years ago, and about 70 double deckers were in service in March last year.
The 287mm recorded by Niwa this week is 216 per cent of its normal rainfall for January-February.
The Metservice and Niwa are predicting a wet start to March for the upper North Island as well, as the tropics take control of our weather systems.
Auckland's public transport use has been steadily increasing, with 91.1 million boardings for the 12 months to December 2017, an increase of 7.4 percent, or 6.3 million boardings, in the 12 months to December 2016.
March is regarded as peak month in the year for transport, and two years ago there were 1157 complaints about buses being late, full, overcrowded or not showing up.
However, some services will be very busy, Ireland said.
"We are confident our customers will be able to get on services but there may be some queuing. Some people will have to stand and in some cases the first bus might be full.
"We're confident we have sufficient capacity but we will be monitoring key routes and adding capacity where it is needed."
The increases before March last year, and greater capacity provided in June and December as part of full service network upgrades in West and East Auckland, provided a good base for annual transport demand peak next month, he said.
Most of the extra seats would be temporary unless ongoing demand warranted further permanent capacity, Ireland said.
