Labour says a mix of push and pull factors are responsible for Australia poaching New Zealand cops. 

1News reports 144 New Zealand police officers left for Australia in the past year.  

Police Commissioner Richard Chambers says we can't realistically keep up with the pay and incentives being offered. 

Labour's Police spokesperson Ginny Andersen told Ryan Bridge a major push factor is the Government's failure to deliver on its 500 additional police officers. 

She says there's more pressure for frontline police, with less support and pay compared to Australia.
