But he refused to accept his opponents' arguments that the sector had been under-funded or that the Government had been slow to respond.
Former Police Minister Judith Collins signalled the need for police as early as June last year. English said yesterday the Government had needed time to put a plan in place for tackling crime.
He also said the crime problem was not the result of underfunding but was instead a symptom of a growing population.
Having achieved its long-sought Budget surplus, National was now prepared to "invest up-front in programmes that will tackle ... complex issues", English said.
The significant investment came with performance goals. Among the new targets for police was attending 98 per cent of burglaries within 48 hours, up from current rates of 86 per cent.
The targets would "not be an easy task", Police Minister Paula Bennett said. "But we're here to tackle the difficult issues."
The Labour Party and New Zealand First have both promised more police officers if they are in power. New Zealand First leader Winston Peters has made it a bottom line in any coalition talks.
Both he and Little yesterday said English's policy was too little, too late.
Peters said it was an "election year stunt" which came after years of National saying the crime rate was falling.
"The public won't be fooled," he said.
Little said English was playing "desperate catch-up" and had to be "dragged kicking and screaming" into increasing police numbers.
"Less than a year ago he was the Finance Minister who signed off on a four-year freeze on police numbers," he said.
Little also said the policy was a "skinny version" of Labour's promise to introduce 1000 more cops within three years. Peters wants 1800 police within five years.
In anticipation of any criticism, English sent a warning about other party's election promises and their costs in election year, saying voters should "look beyond the dollar-figure sound bites".
The package also included measures to make police more available and visible, including a 24-hour phone line for non-emergencies and funding the Eagle police helicopter to run around the clock.
Police Commissioner Mike Bush said some criminals in Auckland had learned that the helicopter stopped operating at 3am, and crime often spiked after this point.
In an unusual move, Bush attended the policy announcement yesterday and supported it in statements to media. He denied overstepping his role as an impartial public servant, saying it was an important issue for his department.
