It's while Canterbury grapples an outbreak, which has seen 27 people in the region contract the disease.
A Sydney baby - too young to receive their routine measles vaccine - also developed the disease after arriving home from the Philippines.
The symptoms of measles symptoms are a cough or runny nose or conjunctivitis, and a fever above 38.5 C, and a rash.
Fourteen thousand does of the measles, mumps and rubella (MMR) vaccine are now being distributed to Christchurch general practices as the number of confirmed cases of measles has risen to 28 almost three weeks after the outbreak began.
Wellington issued information sheets about the highly-contagious disease to early childhood centres and schools.
The Auckland Regional Public Health Service is asking people who may have been exposed, to look out for symptoms.
On Monday the Canterbury District Health Board confirmed 25 cases, adding in a statement that it was likely the number of infections would rise. "And the second dose of the vaccine is for that small percentage who do not gain immunity from that first vaccine", he said.
"We know that one dose of measles vaccine including MMR protects 95% of people against developing measles".
"New Zealand usually uses about 12,000 doses of the MMR vaccine a month. the vaccination programme in Canterbury has no impact on stock levels for the childhood immunisations schedule in New Zealand", Pharmac director of operations Lisa Williams said.
People are being encouraged to get themselves immunised in order to contain the spread of measles.
Wrapped up in the outbreak is an anti-vaccination movement with proponents known as anti-vaxxers, who argue the measles, mumps and rubella or MMR vaccine causes autism even in the face of science that has debunked the claim.
Anyone who suspects they may have measles should stay away from work, school or public places to help prevent putting others at risk. This also applies if you or a family member aren't fully immunised and may have been in contact with someone with measles.
