The challenge has been issued and the NZ Zealand Police have accepted.

And now police are challenge the NZ Fire Service, St Johns, NZ Defence Force, Surf Life Saving New Zealand and Red Cross to take up the Burpees for Babies Challenge.

Plunket is challenging New Zealanders to get creative this National Children's Day (today) by doing five burpees for under-fives. ‘Burpees for babies' asks people to do five burpees, video their effort and load it to Facebook asking five other people to donate to Plunket and do the same.

Burpees for babies aims to raise money for Plunket's community services as part of its Raise a Bundle campaign. The campaign will run for the month of March and aims to raise $10,000.

So far Wellington Mayor Justin Lester, The New Zealand Police and Les Mills Lower Hutt have said they will put their fitness to the test to raise funds for Plunket.
