National's health spokesperson Dr Shane Reti has released the five steps he says the Government can take immediately to keep New Zealanders safe from the coronavirus.

"National has developed a detailed border plan that will keep the virus at bay while allowing our economy to thrive. New Zealanders deserve this rather than the ad-hoc system that is currently in place," he says in a statement on Sunday.

"As well as this improved border plan, there are five practical steps the Government could be taking right now to keep New Zealanders safe."

Dr Reti's five-point plan:

1) Genomics re-testing

Re-test people for genomics within 24 hours of every positive case.

"Increasing the number tested would help us identify linkages and the heritage of the virus," Dr Reti says.

2) COVID-19 test times

Require a negative COVID-19 test turn-around time of 48 hours.

"People have been using up all of their sick leave waiting days for negative results," Dr Reti states.

• Five new COVID-19 cases in New Zealand
• People are starting to lose patience
• One case 'under investigation' in Canterbury managed isolation - Ministry of Health
• Chris Hipkins hits out at 'deliberate misinformation' on COVID-19 vaccines

"It is important positive tests continue to be the priority and reported in 24 hours. But negative tests should be tightened up with a measurable target of 80 percent of negative tests reported in 48 hours."

3) Record declined tests

Require people who have been declined tests to be recorded in the National Contact Tracing Solution.

4) Compulsory managed isolation testing

Make day-three managed isolation testing compulsory.

"The sooner we identify positive cases who have crossed our border, the more effective and safe our response is," Dr Reti says.

5) Improve app

Improve the COVID-19 app so that it can display information as well.

"Currently the app can pull location information from what is being scanned, but it would be more effective if it could also share user information," Dr Reti states.

"This would make the contact tracing system much more efficient and effective as people could be identified quickly."

'We need to move quickly'

"We're in the middle of a second spike of COVID-19 and we need to move quickly. I encourage the Government to consider these five proposals to raise our collective bar and protect us all," he says.
