The first review of the Alert Level 4 lockdown in Wales is set to take place this week.
First Minister Mark Drakeford placed Wales in the highest Covid tier on December 20 in a shock announcement as cases increased.
This saw all hospitality, leisure and non-essential retail closed and a stay at home message issued.
Since then the overall seven day infection rate in Wales has fallen but has increased in areas like North Wales where rates had previously been far lower than the national average.
The national average of around 450 remains in the range for Alert Level 4 - with a figure under 300 part of the criteria to move to Alert Level 3. Level 3 would allow all shops to reopen and hospitality to trade under strict rules, like a ban on alcohol.
Parts of north west Wales, mid-Wales, and west Wales remain below 200 cases per 100,000 and there had previously been calls for different tiers within Wales.
But even here counties like Anglesey have spiked - going from 27 per 100K in mid-December to 165 in the seven days to December 29 despite lockdown being in place.
Hospital chiefs in North Wales have also warned of an increase in serious cases in its intensive care wards.

There were 2,610 Covid patients in hospital across the country on Wednesday. This ranges from 11% of all patients in Betsi Cadwaladr health board covering North Wales to 52% at Cwm Taf Morgannwg in South Wales.
It is against this backdrop that the Welsh Government cabinet will meet this week to discuss the latest Covid restrictions.
Ahead of those discussions Mark Drakeford said it was "very hard to see where the room for manoeuvre is at the moment" with the NHS "under huge pressure".
He told the BBC he does not "see much headroom for change".
Without further changes, restrictions could be kept until the next three-week review - meaning lockdown continuing until the end of January.
Mr Drakeford also said the Welsh Government was unlikely to tighten restrictions despite the emergence of a new more contagious ariant of the virus - which has led to calls for schools to remain closed for a longer period.
He said there could be some tweaks "at the margins" but no wholesale changes because "it's difficult to see what more could be done".

The extended lockdown will place further financial strain on businesses in the hospitality, retail, tourism and leisure, with warnings it could push some over the edge.
Welsh Government has been urged to increase the financial support on offer and the speed in which grants are handed out.
ERF Restrictions Business Fund grants of up to £5,000 have started to be handed out to eligible businesses.
The £180m Sector Specific Grant applications will open on Monday and remain open for two weeks or until funds are fully committed.

This fund states it is to cover the period from December 4 2020 to January 15 2021 so if lockdown does extend to the end of January it is hoped additional support will be provided.
Ashley Rogers, commercial director of the North Wales Business Council, said: "The increase in rates per 100,000 of Covid-19 cases in North Wales is concerning to everyone and public health of course comes first.
"It’s imperative though that when Welsh Government announces its review decision on the Alert level for North Wales, it does so mapping publicly that decision against the criteria it has itself set for that particular level, along with the supporting data and details of much needed new financial support for our businesses.
"This would give our local businesses, workers and communities the transparency we all need that there is a set process for entering or exiting levels and therefore some degree of certainty on the direction we are headed.
"It is superb to see the roll out of two vaccines in North Wales but the key Easter trading period will be on us before we know it and our businesses desperately need to understand now not later, the clear process and evidence on decisions being made, when they impact them directly."
