Inland Revenue says it will offer people leeway of up to one week to pay outstanding tax as long as they get in touch with the department.
The tax department's online login site myIR was still experiencing some technical hitches this morning as the official deadline for bill payments - 5pm today - loomed.
After a five day shut down, which began at 3pm Thursday, some users were still struggling to log on this morning to check their account details.
On Friday the IRD said it would give some leeway to people who can't make payments ahead of a February 7 deadline because of the shut down.
Today a spokesman confirmed that "this leeway will be for up to one week, providing customers get in touch with us over the next few days and pay their outstanding balance by February 14."
Inland Revenue's customer services shut-down at 3pm Thursday but was due to go online again at 8am this morning to make way for changes the department is making around GST.
