Northland, and possibly Auckland and Coromandel could also expect some "wetter conditions" due to a hint of low pressure.
Extreme temperatures so far this summer have caused headaches for farmers, with many having to de-stock farms due to drought like conditions.
Ms Blades predicted more dry weather was on the cards for the rest of the month.
She said while more rain was expected this month than in January, February was traditionally a "warmer and dryer" month.
"January was so dry we just had that little bit of rain right at the end of the month, and then we had that nice band of rain that moved up the country yesterday which brought some quite good falls to most places.
Weatherwatch.co.nz analyst Philip Duncan also predicted dry and warm weather for the rest of February.
He said while the start of February was unsettled with rain and cooler air, a large high was rolling back in. This meant calmer, drier and hotter was about to return to most of the country.
Mr Duncan also did not predict much rain for New Zealand over the next week or two.
"In fact a large high may well remain firm over most of the country for the rest of February...which is why we are still very concerned about droughts being officially declared in some of our driest regions later this month."
Firefighters in the central North Island and the South Island have also been kept busy with a number of rural fires that have broke out this summer.
A fire that started last Tuesday and ripped across about 400ha of farmland near Onamalutu, in southern Marlborough, was still being monitored by fire crews, to ensure hot spots did not flair up.
With dry conditions set to continue the New Zealand Fire Service was urging people to be careful.
"The hot dry conditions are continuing to bite, as shown by a rise in the number of large rural fires.
"People are generally being very responsible and that's fantastic. We want everyone to be especially careful, to respect fire restrictions and to be mindful of their individual actions."
