People in England who refuse an order to self-isolate could be fined up to £10,000 (NZ$19,000), the government has said.

The new legal duty requires people to self-isolate if they test positive for coronavirus, or are traced as a close contact, from 28 September.
New measures also include a one-off £500 (NZ$955) support payment for those on lower incomes, and a penalty for employers who punish those told to self-isolate.
It comes as Prime Minister Boris Johnson considers tightening restrictions after a surge in cases.
A further 4422 new Covid-19 cases and 27 deaths were reported on Saturday.
There were 350 new cases reported in Scotland, the highest daily increase since May, 212 new cases in Wales, and 222 in Northern Ireland.
Fines will initially start at £1000 rising to £10,000 for repeat offenders, and for "the most egregious breaches". Up until now, advice to self-isolate has been guidance only.
Johnson said: "So nobody underestimates just how important this is, new regulations will mean you are legally obliged to do so if you have the virus or have been asked to do so by NHS Test and Trace. People who choose to ignore the rules will face significant fines.
"We need to do all we can to control the spread of this virus, to prevent the most vulnerable people from becoming infected, and to protect the NHS and save lives."

Warning of more measures
Health Secretary Matt Hancock said the nation was at a "tipping point" and warned more measures would be brought in unless everyone followed the rules.
"I don't want to see more measures but unfortunately if people don't follow the rules that's how the virus spreads," he told Sky News.
Asked if he would report anyone he knew breaking the rules, he said: "Yes. And everybody should."
More than 19,000 fines have been issued in England and Wales for alleged breaches of coronavirus laws, the attorney general said earlier this week, but more than half have not been paid so far.
Labour leader Sir Keir Starmer told Sky News he supported the new fines, saying "a small number of people are breaking the rules and something has to be done about that".
But he warned it was not a "silver bullet" while the testing system was "barely serviceable".
Those attracting the highest penalties are described as including those who stop other people from self-isolating, such as an employer who insists a staff member comes to work in violation of an order.
The penalties are in line with those for people who fail to quarantine for 14 days after returning to the UK from a country not on the list of low risk nations.
In Bolton, one returning holidaymaker, who did not self-isolate and instead went on a pub crawl, is being partly blamed for the town's spike in cases.
The UK government hopes the new measures will be replicated in Wales, Scotland and Northern Ireland - which all have powers to set their own coronavirus rules.
Officials said NHS Test and Trace would be in regular contact with individuals told to self-isolate and would report any suspicions that people were not complying to the police and local authorities.
Police will also check compliance in Covid-19 hotspots and among groups considered to be "high-risk" as well as following up reports from members of the public of people who have tested positive but are not self-isolating.
Prosecutions could follow in "high-profile and egregious" cases of non-compliance.
As with other coronavirus rules, there will be specific exemptions for those who need to escape from illness or harm during their isolation, and for those who require care.
Changes to support for those in receipt of benefits or on a low income will initially affect up to four million people who cannot work from home in England, the government said.
The one-off payment of £500 (NZ$955) is above both statutory sick pay of £95.85 (NZ$183) per week and a previously-announced additional award of £182 (NZ$347) for those told to self-isolate in highest risk areas of intervention.
