In an internal police memo sent yesterday and obtained by the Herald, Police Commissioner Peter Marshall put no deadline on the deferment.
"A low attrition rate and the need to live within our current baseline funding means we're being very conservative in terms of our planning for next year," he said.
The memo said the only decision made so far was to defer the January recruits. It does not mention March.
"Other wings will be confirmed once we've analysed our requirements ... base recruitment lines remain open."
Police are making savings to fund other initiatives; national headquarters and the police college were asked to find 15 per cent savings, while each district was asked to find 5 per cent.
Mr Marshall, who usually comments on operational matters instead of the minister, refused interviews yesterday.
Prime Minister John Key and National's campaign chairman Steven Joyce both called Mr Goff desperate, while Ms Collins said he was "not being truthful". She called his statements a stain on his legacy.
"Phil has gone on national TV and made these allegations, based on what somebody told him somewhere. This is outrageous behaviour."
Ms Collins challenged Mr Goff to name his source, adding that "any fool" could make claims without naming names. "I say to Phil: Front up. Think about your legacy. Do you want to be known as the person who tried to undermine public confidence in police, their political neutrality?
"And apologise to the Police Commissioner. He deserves more respect ... You don't go around accusing police of being part of some political cover-up."
She said she did not ask Mr Marshall if there had been police plans or discussions to defer recruiting until the end of next year.
"But I've spoken to the Police Commissioner, I'm the Minister of Police, we're not cutting that frontline - and that's it."
Police Association president Greg O'Connor said the minister's comments were reassuring.
"And we hope there is no further deferment."
Last night Mr Goff said his sources had since told him that recruiting had been cancelled for January and February. "When they started talking about March, I don't know. Maybe it was after the debate.
"They got caught out. They're trying desperately to heap abuse on me to reduce their embarrassment."
